Still not as bad as kwh/hr. That one is showing up on some car UIs now.

- osigurdson 4y agoWhy can’t we just use the right unit for energy - Joule? A battery capacity should be stated in MJ / GJ.
- danuker 4y agoAn hour is a popular unit for me personally. I measure my work and plan my day in hours (since pretty much all clocks use hours, not kiloseconds). I don't use seconds very much (with the exception of Unix epoch seconds, or a short experiment). I can't divide by 3600 in my head. I can, however, multiply by 1. Therefore, Watt-seconds (AKA Joules) are not as useful to me as Watt-hours and kiloWatt-hours.
- osigurdson 4y agoNatural gas is consumer priced in GJ and seems to work fine. Eventually we would just develop and intuition about number of K/M/G J in various battery sizes without the complex/ugly kwh unit.
- _ea1k 4y agoI hear this occasionally, but what are the benefits relative to kwh?
- osigurdson 4y agoIt basically comes down to stating things in their simplest and most correct form. It is like using 75/25 to express the number 3. When expressing an energy value, use the right unit (Joule) not a derived unit multiplied by another quantity to get back to the original.
- pfdietz 4y agoThat's at least dimensionally correct.
