Okay, search engines can never replace a trained librarian, but

I love to be able to Google anything and normally find something to help me with my question. For example, I weighed myself this morning, and decided to see how different it was between morning and evening. But somehow my scale got set to kg when I pulled it out from its place this evening. I didn't see anything, tried resetting it by taking the battery out, and when that didn't work, went to Google. Apparently there's a switch that's on there but it's the type you depress to toggle the unit of measure on the back, and I'd accidentally managed to depress that. I turned the scale on (you step a foot on the scale to do that), depressed the switch, which does blend in with the rest of the underside, and I had pounds rather than kilograms again. And oh, by the way, even though I'm not having swollen ankles like I did when it was hot, I'd gained 8 lbs in water weight over the course of the day, which is why I don't consider it significant until about 15 lbs. Yesterday, I weighed myself with clothes and shoes on (I don't normally do that), and it was 10 lbs higher than this morning.
