KM vs Miles

[Dogtrousers]

What tyre pressure do you run?

Oddly enough I use bars because my track pump happens to be in bars. I didn't choose it for that, TBH I didn't check when I bought it. But it is, so that's what I use.

Fair enough. I was taking a punt that like the vast majority in the UK you'd think in PSI.

I do actually think for the specific use case of road cycling, PSI makes a lot of sense as you're basically operating on a scale of roughly 1-100.

road signs in miles , measure in miles

Agree!
I was born and attended school on the continent, brought up with the metric system.
When I started cycling here in the UK I adopted miles for my distances, because the road signs are in miles.

What tyre pressure do you run?

I use PSI, don't know why, always have.
I vaguely remembered the unit from my youth (never had to use it then), so, when I needed to pump up tyres later in life that's the unit I started using.

I must admit I just pump them up until the needle is roughly in the middle. I have to admit I don't really look at the numbers (I think the middle is about 5 or 6 bar, don't know how many PSI).

If your using a track pump, it’s likely to be wildly inaccurate. For real tyre pressure you need to use a proper pressure gauge or second best one of those battery/ electric pumps.
This is according to GCN so it must be true.😏

When I started cycling I never saw such a thing as a graduated pump. I had no clue what my tyre pressure was and it never did me any harm.

So you think. Maybe your decline in performance is nothing to do with ageing it all do to tyre pressure.😱

Until recently, I always had my Wahoo showing miles, but with climbing in metres, while I use imperial for Strava (that doesn't give the choice of mixed units). Recently, I've started showing Km on my Wahoo (partly because I decided on 60Km as my distance for this year's Lunacy challenge), but I still have Strava showing imperial.

I'm another one who works in miles, however thanks to the monthly challenge thread I take part in being in KM I do plan for at least 31 and a bit miles.

I've noticed that when discussing distance in the forum bods always seem to refer the the number of kilometres rather than miles, even when UK travel. Is this a cycling thing? Just curious

It's a human powered travel thing. Most, but not all, running and cycling challenges are in km. It's also easier to divide the distance by 4 (who am I kidding?), 5 (on a good day!), 6 or 8 (more realistic, summer to winter) to figure out how many hours it will take to cycle.

Guess you have to be late 60s to have not been educated from primary school in metric?
imperial is an utterly daft and illogical system. Metric just relates logically

Imperial is more based on what people could see and feel in the old days
so a yard is a step
an inch is the length ot the top part of a man's thumb
an acre was how much land a horse could plough in a day
etc etc

a lot fo which still works

it is just that when you start doing maths with it Imperial gets complicated
and metric just makes more sense

I remember my first 100 mile ride, and (humble brag) my recent first 100 mile run. Can't say I remember my first 100km ride.

 

[tyred]

I measure my ride distance in Millimeters. It sounds much more impressive.

When I was younger I always said miles are for men kilometers are for kids, now I am older kilometers sound good.😂

Imperial gives me a headache because all the multipliers are different. Fortunately, I was born just after Australia adopted metric. One or two things have carried over from those days: I'm equally comfortable thinking of my height as just under 6'3" or as 1.9m.
