10 W/sq ft is 107 W/sq m.
- kragen 7y agoThank you for the correction! My calculation error (I had written "11 W/m², 90 times less than direct sunlight"), though unintentional, is an excellent demonstration of why using medieval units is a bad idea.
- Dylan16807 7y agoBeing off by a factor of ten is very easy with SI units too. Centimeters vs. millimeters for example.
- kragen 7y agoYeah, and I've certainly made that mistake more than once. (I try to avoid using centimeters or centi-anything for that reason, as well as deci-, deka-, and hecto-.) In this case, though, the calculation I biffed was a unit conversion from medieval units to modern units. It's harder to get calculations wrong when you don't have to do them at all.
