Hi All

Can someone give me the aogorithm to convert min/mile into min/km please??

At present I

1. Convert miles to Km

2. Convert my time to in minutes into

seconds.

3. Divide seconds by distance in Km.

4. Divide this answer by 60 to get min/Km

ie.

6.2 miles = 10K in 43:17

43 X 60 = 2580 + 17 = 2597 seconds.

2597 / 10 = 259.7 seconds /Km

259 / 60 = 4:19 min/Km approx

Is this correct or is there an easier way.

Please forgive the basic maths question but my schooling was done in the time of imperial measurements

Cheers,

MK

either convert your time to seconds

i.e. 4:19 = (60*4) + 19 = 259secs/mile

or convert it to metric style

i.e. 4:19 = 4 + (19/60) = 4.317mins/mile

divide by 1.6 (miles->km)

161.9secs/km or 2.697 mins/km

and work back into whole minutes & seconds..

in a rush.. just realised i started with your example min/km time but the principle stands .. i think

Easiest is on a spreadsheet. Problem is mixing decimal and hh:mm:ss units.

Cannot suggest easier way with a calculator only a different one

Convert seconds into decimal ie secs/60, 17/60 = 0.2833 and add minutes = 43.2833

divide by the km ie 43.2833/10 = 4.3283min/km.

Convert decimal back to secs by multiplying by 60 ie 0.3283 x 60 = 19.7

Result 4:19.7 min/km

Thanks, but could you add an example please ??

ie. From above

6.2 miles run in 43:17

To convert miles into kilometers, divide by .6214

6.2 / .6214 = 9.97747 = 10K

43:17 - 6:59 min/miles

How now to convert to min/Km ??

times by miles divided by 1.609 = times by km

Thanks peeps.

so if you're rounding up to 10k then your time per km is 4.3283 min which is approx 4:20 (4:19:something) which is what you got on message 1, give or take fractions of a second.

Thanks Gavo.

Here is something I found while surfing for information on conversion algorithms. Some of you guys might find it useful.

Rule of thumb: 1Km = 0.62miles. 1mile = 1.61Km.

To convert kilometers into miles, multiply by .6214.

To convert miles into kilometers, divide by .6214.

In detail:

1Km = 0.62miles

2Km = 1.24miles

3Km = 1.86miles

4Km = 2.49miles

5Km = 3.11miles

6Km = 3.73miles

7Km = 4.35miles

8Km = 4.97miles

9Km = 5.59miles

10Km= 6.21miles

1miles = 1.61Km

2miles = 3.22Km

3miles = 4.83Km

4miles = 6.44Km

5miles = 8.05Km

6miles = 9.66Km

7miles = 11.27Km

8miles = 12.87Km

9miles = 14.48Km

10miles = 16.09Km

5:00min/mile = 3:06min/Km

5:30min/mile = 3:25min/Km

6:00min/mile = 3:44min/Km

6:30min/mile = 4:02min/Km

7:00min/mile = 4:21min/Km

7:30min/mile = 4:40min/Km

8:00min/mile = 4:58min/Km

8:30min/mile = 5:17min/Km

9:00min/mile = 5:36min/Km

9:30min/mile = 5:54min/Km

10:00min/mile = 6:13min/Km

10:30min/mile = 6:31min/Km

11:00min/mile = 6:50min/Km

12:00min/mile = 7:27min/Km

3:00min/Km = 4:50min/mile

4:00min/Km = 6:26min/mile

4.30min/Km = 7:15min/mile

5:00min/Km = 8:03min/mile

5.30min/Km = 8:51min/mile

6:00min/Km = 9:39min/mile

6.30min/Km = 10:28min/mile

7:00min/Km = 11:16min/mile

7.30min/Km = 12:04min/mile

8:00min/Km = 12:52min/mile

The postings above provide a full answer I think, but if you want to get seriously anorakky then download the little program from the website below:

http://www.joshmadison.com/software/convert/

It is a seriously brilliant and simple piece of software (and its free!)

It will convert just about any imperial unit to a metric unit, or the other way round.

Although you could set it up as a custom unit, or alternatively e-mail the author and he may incorporate it into the next release (which tends to be quite frequent)

Easy rule of thumb

miles *8 / 5 = km

km * 5 /8 = miles

The approximation is 0.625, but the actual is 0.623 so its only 0.3% out.

If you want to take your mind off things when you are out running try to do it in your head!

BTW 8min/mile = 7.5mph or 12.1kph

10 minute miles is real easy to work out - 6mph!

There you go - one benefit of plodding is simpler maths.

and what about furlongs / fortnight .....
