cycle computer – miles or kilometres?

    Hi all,

    I guess this question is mainly aimed at the UK cyclists on here.

    If you use a cycle computer / odometer, do you have it set up to read miles and MPH, or kilometres and KPH?

    I’m just calibrating my new one, and trying to choose. Always used miles on my old one, but am tempted to go metric. How many of us have done so?

    Could it be a poll question, maybe?

    I have miles on mine and my other half has KM on his – best of both worlds.

Although this instance is perhaps ultimately harmless, it is particularly sad to see when it creeps in to our wonderful sport.

    Yep – metric and mental
    Yep – metric and mental calculation it is, then.

    The final straw was realizing (thanks to Sheldon Brown’s site) that most cycle computers, mine included, “think” natively in cm or mm.

    His point is that not all computers use an accurate conversion factor. They should divide the km by 1.609344 to get miles. But some lazy programmers just used 1.6 instead. So I’m going with km.

    Personal choice I guess, and shouldn’t be too difficult a decision to make since whatever you’re on it’s easy to do a mental calculation to see what it is in the other :B Having said that, miles would appear to be the logical choice for UK.

    I went metric initially
    I went metric initially because I could calibrate my computer more accurately with mm than inches. Decided to leave it that way, partly because I know 0.1km is 100m whereas I didn’t want to figure out tenths of miles in feet or yards (maybe that’s my less than stellar ability at maths). I prefer it, though I find I still mentally convert to mph when checking my speed out on the road. Rough guide:

    kmh / mph
    16 = 10
    25 = 15
    32 = 20
    40 = 25
    50 = 30

    Anything more than 50km/h is too fast to be staring at the computer!

    ” luckily the Garmin 705 lets you have a combination of both imperial and metric for different measurements.”

    Maybe this is the best of both worlds. Bizarrely, my cycle computer only lets you choose miles or km, mph or kph, when you first turn it on. (free Kellogg’s one, so i can’t complain).

    Reassuring, that UK cyclists are using km.

    I would have opted for miles but the shop set the computer to kph. I didn’t want to re-set it as I wanted to use the odometer as a guide for when to return the bike for its first service and now have got used to kph so will stick with it.

    I use miles an hour for speed
    I use miles an hour for speed when in the UK, but change to kilometres an hour when abroad.

    I always use metres for height gain though, luckily the Garmin 705 lets you have a combination of both imperial and metric for different measurements.

    I am metric. 30 kph seems so
    I am metric. 30 kph seems so much better than 18 mph. And it is much easier to see how pathetically slow I am compared to the pros. I mean, when I’m really going for it, I sometimes reach the average speed for the entire Tour de France!

    I’m in a similar boat, always been miles but considering metric – just wondering how long after a change it will take for me not to convert to mph mentally!
