Sooner or later, the whole world should adopt the SI and the 1000s rule.
Weather should use kPa rather the hPa to be consistent with other industries.

Mike,
Are you saying that same tire sold in the US would be marked in kPa (psi) but
when sold in other countries would have bar and kg/cm2? Why not make the same
tire for the whole world? It seems costly and confusing to do otherwise.

I think what you see on tire walls is the maximum pressure in kPa. As the
Pascal was only implemented in SI in 1971, countries that used the metric
system prior to that tended to stay with the older units like Bar and kg/cm2.
On the inside driver door pillar of all US cars is generally the recommended
tire pressure in kPa and PSI.

Martin,
My tires show kPa (psi). Is this also the way it is in the world or only
the US?

The most common units of measure for tyre pressures in Europe are bars or
kPa. (100 kPa = 1 bar).

Harry,
Aren't they suppose to be in pascals or something along that line?

A minor point of interest: on PBS's US broadcast of the BBC World News
tonight, in a piece re the resumption of natural gas to Europe, there was
"footage" showing close-ups of presssure gauges on pipeline fixtures out in the
snowy fields. One showed pressure in kg/cm2, and the other in "bar".
