| > Ask a German what their car's power is in kW. > Other examples are screen sizes that's common, but not as units of measure, but as marketing. Same as megapixels in photo cameras. Nobody measure power in HP, we say "that car has 85 HP" only in speech, but when it matters (for example on car papers) power is express in KW and screens are measured in cm that are also written on the package, they are only marketed in inches. You would be correct if people had an idea of how much power 1 HP is or the surface of 1 MP camera shot, but they don't know, they only know that 16 MP > 12 MP and 300 HP > 100 HP, they (we) ignore what it actually means. It is also perceived completely differently depending on context. A 120HP tractor is not the same thing than a 120HP car or a 120HP motorbike. According to US measures I'm 5'11, which means nothing to me, while it's obvious to them, because they actually use foot and inches all the time and do math using them. Also 90F means nothing to me. |
