On the contrary Fahrenheit and Celsius is one of the harder units to convert. Can't just "halve and remove 10%" in your head like you can for pounds. Though I agree with you that you can't expect Americans to use SI units.
- Broken_Hippo 4y agoMost folks reading this will have the internet. It makes conversion easy. If you don't, charts help get most common things converted. Easy.
- rsfern 4y agoThe scale factor is 9/5, which is close enough to 2 that the precision is fine for casual conversion (weather report, discussion of boiling tea on the web, …)
- coffeeling 4y agoDefinitely not. Say, 86F to C. 86F is 30C, but dividing the F by 2 would give you "43C", which converts to 109F. That is not a trivial difference.
