Km.--Miles converter
Can anyone give me a website or easy way to convert Km. to miles. You see lots of currency converters--a milage one would be nice! We will be driving in Ireland in about three weeks.

You don't need a converter if you can remember how to do sixth grade math. All you need to remember is that kilometers are shorter than miles, and one mile is about 1.6 km. For ease of conversion, use a factor of 0.6 to multiply km and arrive at miles. To convert miles to km, multiply the miles by 0.6 and then add the original number of km to the result. Or divide the km by 0.6 to get the miles. These results will be accurate to within a few percent, which is plenty good for us travelers.

Distances in Ireland are calculated in miles, not kilometers, Pat. You needn't worry about conversion factors.
|
The lovely thing about Ireland's road signs is that SOME of the distances are shown in miles, some in km, usually without an indication as to which is which. Don't worry too much about it, you'll get there sometime....
|
Divide miles by 5, then multiply by 8 to get kilometres. I.e., 50 miles = 80 kms.<BR>Divide Kms by 8 , then multiply by 5 to get miles.

Divide kilometers in half and add 10% of the original number. 120 km = 72 miles (approx)

Do rental car odometers in Ireland measure miles or kilometers?

>Do rental car odometers in Ireland measure miles or kilometers?<
The newest ones with electronic odometers do both. The newer ones do either miles or km. The very old ones measure in furlongs. |
Why does it matter, 100km is longer than 10km it's all relative, if the speed limit is 120km then you don't do much over that. Currency is different, you have to pay for that out of your native currency so a conversion is very important. Distance is distance don't worry about such little matters, and as people have said some basic mathematics will solve this burning issue.
|
The odomoter will have your SPEED in km and miles. HOWEVER, your distance traveled will be in Kilometers. |
Our experience too is that the odometer's always been in kilometers (std Euro setup). Most distance road signs have been in miles, but not all. As said on one of the older posts - sometimes you just can't tell which it is. Driving in Ireland is a lot of fun, but moreso when you just take to trip at its own pace. |
Odometer in kilometers (unless the fancy variety as seen on some US models). Speedometer in both. |
to estimate, multiply the KM times 6 and drop the last digit.
60 km becomes 6 x 60 = 360 means 36 KM 100 kph 6 x 100 = 600 means 60 mph |
The way I learned it was to multiply miles by 5 and divide by 8 to get kilometers. Still works for me.
|
Personally, you shouldn;t worry about any of it.
If you do then the ONLY number you need to remember is "point 6" (.6) To get miles from that 120 Km above, MULTIPLY it by .6 120 X .6 = 72 miles To get Kilometers from those miles then DIVIDE by .6 72 divided by .6 = 120 Km FORGET about the "sixth grade math" multiplying by 5 and dividing by 8, adding whatever "percent" etc. While these other people are still doing the "hard math" calculations, you'll already have arrived. Enjoy your trip! |
And when you get home, start campaigning for the United States to drop those antiquated British Imperial measurements and go metric (it's less painful than you'd think).
|
a foot note to the posts that say "you can't tell the difference on the signs if the distance is in miles or Km. You can -
older signs in miles - white background black writing new signs in Km - green background white writing |
If you're driving a car with both mph and kph shown on the speedometer (usually one set of numbers under the other) you can quickly convert roadsign distances by just looking at the speedometer scale - for example, you'll find 100 kph just under (or over) 60 mph, therefore 100 kilos = 60 miles, etc.
|
Nah, metric is sooooooooo boring. Down with the cookie-cutter approach to life.

St. Cirq -- you've it the other way around, I think.
1 mile is approximately 1.6 km = 8/5 km. 1 km = 5/8 mile. |
that's right but St Cirq has it correct, I think you'd aren't reading or understanding what she wrote.
I don't do this complicated two step stuff, either, dropping decimal pts, multiplying first by one no. then another, etc. This is simple math since 1 km is approx .6 mile. If one knows basic algebra, you can go from miles to km and back. I just divide the km by .6 to get miles, as that's what I want to do in Europe. (It is actually .62 mile, which is why the 5/8 thing works). There is a real neat online web site that converts anything, though, called www.onlineconversion.com |
Hm... Now, Christina, he/she wrote:
"The way I learned it was to multiply miles by 5 and divide by 8 to get kilometers. Still works for me." Ok. Take an example. 1 mile. Multiply that by 5. Divide by 8. You get 5/8 or 0.625. That's not right. It should be 1.6. He/She inverted miles and kilometers. Did I read this wrong? |
Yes, 1 km is approximately .6 miles. So you multiply, not divide, kms by .6 to get miles. I'm pretty math-impaired, but it becomes second nature after a while.
|
No, 111op, I think it's you who have it backwards. Or perhaps I have lost my mind.
|
I stand by what I wrote. StCirq, can you follow your instructions and give us a calculated example?
As I wrote, 1 km = 0.625 = 5/8 mile. 1 mile = 1.6 km. Your recipe, if I follow it, when converting 1 mile to 1 km, will give a number smaller than 1. |
RufusTFirefly, you might just have me there - I have to admit that your approach ("metrics are boring") has a certain offbeat appeal. So why not go the whole hog and return to pounds, shillings and pence? Being old enough to remember that system (as well as Imperial measurements) I can tell you that learning to subtract £4.18s.7-1/2d (spoken as "four pounds eighteen and sevenpence-ha'p'ny" from £8.6s.4d ("eight pounds six and fourpence") gives a whole new meaning to excitement in primary school.
Actually I wrote my post straight after trying to help an American visitor deal with Australian petrol (gas) pricing, a multi-step process leading from AU$ per litre to US$ per US gallon (3.785 litres). I decided that life was complicated enough without that, so I'm happy to get my kicks in other ways. But as you guys say, diff'rent strokes..... Pat, one thing I noticed while driving in the US is that even though I knew very well that 100 miles to the next town was 160 km, at another level what lodged in my brain was "one hour" when I saw the "100" sign, with the result that those 100 miles tended to drag. So, look on the bright side - you might be pleasantly surprised at how fast you get around Ireland. As long as you get the right sign, of course. |
Sorry, St. Cirq, you haven't lost your mind, but you are misstating this. Let's break this down a bit more. (I have to go through a process like this every time I first learn to a convert to any currency, or else it doesn't penetrate my skull.)
Multiplying times 5 and then dividing by 8 is really just multiplying times 5/8. (Remember when you first learned to multiply times a fraction?) Multiplying miles times 5/8 would be correct if 1 mile were about 5/8 kms. But it's not. One mile is about 8/5 kilometers. Miles are longer than kms, which is why any given distance has fewer miles than kms. So for miles to kilometers, multiply by 8/5; for kilometers to miles (which was the original question), multiply by 5/8. And that's why I find .6 easier to work with and close enough for me! |

I was absent the day they taught fractions and algebra. I simply deduct 1/3 off the Km and get pretty close to the Mi. Can't be bothered to add, then divide and with decimal points thrown in somewhere - oh, pleeeese! I don't really worry if I'm off a mile or two - it's close enough. Simplify things.

Km to miles -
Divide by 10 Multpily answer by 6 |
StCirq is wrong. 111op is correct.
This is a trivial conversion. Think about it. If London is 50 miles away from Cambridge, it's 80 kilometres away (roughly). Therefore to convert FROM miles TO kilometres, your conversion factor must make the answer BIGGER. Therefore when StCirq states "multiply miles by 5 and divide by 8 to get kilometers.", you are multiplying miles (the smaller value) by 5 then dividing by 8. In my example that would mean take your original 50 miles, multiply by 5 to get 250 and then "...divide by 8 to get kilometers." which comes to just over 31km. Thus StCirq believes 50 miles is equivalent to 31 kilometers/kilometres. The world is getting smaller, for sure, but the math(s) isn't getting any better... |
Thanks Jimbo. The first thing I did when I came to work today was to check what had happened to this thread (which seemed to have temporarily disappeared. I thought that some overnight flame wars had caused Fodor's to pull the thread. :-)
|
Clearly, I have lost my mind. It must have been the limoncello cheesecake.
|
its real simple :::::
Kilometers / divided by 1.6 / equals and this is your answer for miles. Miles / multiply by 1.6 / equals and this is your answer for Kilometers. theres nothing more and its that simple folks. enjoy |
Ok, I have that. Now, how do I convert Farenheit to Celsius?
|
F = (9/5) times C + 32
C = (5/9) times (F - 32) |
Or maybe it's easier to have some examples:
0C = 32F (freezing point) 10C = 50F 20C = 68F 30C = 86F 100C = 212F (boiling point) |
After skimming the above posts, I agree that it would be nice to use an online converter:

Multiply the KM by 0.6--10Km = 6 miles. It is close enough to one half if you want to approximate as you go.
