Kilo-metres or Kilom-etres

Why has something so incorrect become a standard?

I have noticed that more and more people refer to 1000m as a Kilom-etre. This is incorrect.

It is a Kilo-metre, like all other units in the metric system there is a unit of measurement, a metre and a multiplying prefix, in this case 1000 or Kilo

Kilo-gram not kilog-ram
Kilo-litre not Kilol-itre
Kilo-pascal not Kilop-ascal

Or
milli-metre not millim-etre
centi-metre not centim-etre
nano-metre not nanom-etre

People seem to have adopted Kilom-etre because in the car they also see an
Odom-eter
Speedom-eter

So next time you say Kilom-etre, remember that an Speedometer measures speed, a Odometer measures distance ( odo being greek), a pedometer measures steps but a Kilometre does not measure kills.

I have read that Kilom-eter has its origins in the UK and US, both use Miles so what would they know?

My odometer says 1 kilom-etre and my speedometer says 100Kilom-etres per hour. How dumb is that? I have measured 1 kill and 100 kills per hour.

It's a speedom-eter, and a Kilo-metre
