"My car runs 100 miles!" instead of "My car runs 100 miles per gallon!", and almost anyone would notice something is amiss. I don't get the difference to mixing "Watts" with "Watts/hour".
- pranavjoneja 5y agoEnergy is not Watts per hour (Watts/hour), it's Watts times hours (Watt-hours). Sorry for pedantry, but the units are the topic of discussion here.

- HPsquared 5y agoThat's got me trying to visualise "mile-gallons", and failing because its dimensions would be "length^4".

- firebaze 5y agoI did not imply that at all.
- long_time_gone 5y agoNot knowing the difference in miles and miles/gallon will get you stranded in your car pretty quickly. Now knowing the difference between watts and watts/hour will have almost no appreciable effect on your life. You flip a switch, the light turns on, and you get an invoice a month later.
- tohmasu 5y agoSure, but people writing articles on the subject should know better than to mix units like this.
