  • Well, precisely!

    A watt is a unit of power. It’s an energy rate, it involves time. It’s 1 joule per second (J/s).

    A watt-hour is the amount of energy delivered at a rate of 1 watt over the course of one hour. (J/s x h). And here we get into the trouble already. (The kilowatt-hour is just 1,000 watt-hours, that’s not the source of the trouble.)

    Now we have a unit of energy (the watt-hour) that includes the names of a unit of power (watt, which is a rate) and a unit of time (hour) but the watt-hour (and the kilowatt-hour) measures neither of those things. The watt-hour is defined as ((energy / time unit) x different time unit). It’s insane. Even though the time units should cancel out, we keep the ghost of both time units in the name, to no purpose. It works out to just joules; 1 Wh is 3,600 joules. 1 kWh is 3,600,000 joules.

    Measuring energy in terms of kWh is exactly analogous to measuring distance in “meter-per-second-minutes,” when you’ve got meters right there.




  • I don’t doubt your explanation, but it’s tragic and backwards. It would make sense that a WordPress recipe blog wouldn’t be developed with smaller browsers in mind. But 5% of Instagram’s traffic is a gigantic amount of traffic, worth catering to. Wouldn’t it be the big websites that have both the budget and the motivation to make their sites work across browsers? This feels like a market failure.

    Call me a luddite, but I think if I were BigCorp Website Director, I’d be saying “If you have to do something special to make it work in Browser X vs Browser Y, you’re getting too fancy, you don’t need that crap.”
