You could make yourself a balance and get some calibrated weights. May take longer but probably just as accurate.

Doing a volume mix just isn't as accurate, the weight per volume just doesn't match up.

Why dont you buy a scale. I was at dollar general, and they were selling diet scales for 1 dollar, and they are pretty acurate. They are best when you use a lot at a time.

Good thing you are using a great digital(?) scale.

Do not use cheap shitty spring type scales or most postal scales. I had a postal scale which was incredibly inaccurate. Use the proper scales if you want to get into pyrotechnics.

I use an MX-120 digital scale.

Are the unitednuclear.com's digital scales accurate?
