Thats right. When we make a living we have tools in our hands. The better the tools - the better off we are. When we have fun it is hopefully a brassiere - or a margarita. I am good with either.
Yes. Basically all forms of metrics are now held by science in the form of mathmatical constants and ratios.
Back in the early days of working on the ISS there was a major problem with trajectory. After an in-depth study it was found that it was the result of converting inches to meters an vice versa. When we convert a inch to mm it is 25.4mm When most people change to metric they multiply by .03937 for the answer. In reality the correct number is .03937007.
Now I have a headache.
Actually, one in a billion or one billionth is .000000001, but who’s counting?View attachment 47243
Seriously, when I found out one gram of water is also 1 ml of water, I was happy at the ease of conversion. Now, all I do is measure something of interest and the same volume of water for the specific gravity of that substance against water, and use that simple measurement for grams and vice versa. Ebay sold me a 300 dollar triple beam balance scale for 50 bucks so I am good to .1 grams. The new metric system is accurate to .0000001 I will not be challenging 1 in a billion.
