I normally weigh myself first thing in the morning on Mondays. But today (Wednesday) I weighed myself again, since it's the 1st of the month and I wanted to see how much my weight changed since March 1, when I made changes to my diet.
I use a no-frills digital scale, and round to the nearest pound; i.e., if it says 150.2 I log 150, if it says 150.6 I log 151. I do this because I don't feel it's possible for a home body weight scale to be truly accurate to within a tenth of a pound, and even if it were, I don't feel that bit of information is useful for my health goals.
I used to have a analog scale that my spouse got (for free) from a doctor's office, where you slide the weight thingies along the bars at the top, which was probably more accurate. My spouse also pointed out that you'd get the same results if you weighed yourself with it while on the moon. But it took up a lot of space, so we eventually gave it away.
@funcrunch Yeah, some scales measure mass, some weight.
Technically the usual conversion between pounds and kilos is only good on Earth.
