Thank you John Webster. That made me think, there are alot of things around the house that have the weight stamped on them. The penny thing is perfect. Pennys I have, its dollars I'm short on. Grin

There are 454 grams in a pound and 16 ounces in a pound so a 1/2 ounce wheel weight should weigh 14.19 grams though I doubt that wheel weights are that accurate.

Some other interesting numbers;

Steel (music wire) is .283 pounds per cubic inch.

Aluminum is .098 pounds per cubic inch.

So a 10" length of .032 music wire weighs .002276 pounds or 1.033 grams, 30" weighs 3.1 grams.

A very succesful engineer I used to work for had two rule of thumb measurements that he used frequently; a stick of butter (1/4 pound) and a Cadillac (5,000 pounds). For the purposes of new product and tooling development these were very good visualization tools. Smiley

I'm kinda embaressed about this but here goes:

I played with my scales about a day before I knew what the TARE button was for. Then I saw the instructions on the lid. Brief instructions.
Are there any tips on the care and feeding of elect. scales? Where can I get an official weight to check for acurrate ? I have used triple beams before and once they are "zeroed" they stay that way forever. Is it the same with these little pocket scales?
How acc. can I expect them to be? Are the pricey ones that much better?

Got my cool new scales yesterday.  Cool Odd that they arrived yesterday because that was sunday. Hand delivered by a neighbor from a block away. .....
Anyweigh. Cool new scales say that my Paul Bradley is 7.72 grams without a motor but with a prop. Hope its correct. After work tonite I will use m.c.n.s. to weigh everything in my room. YEA!!
Camera has gone goofy on me so no pic till later . I got it off evilbay for 16 $ free shipping. Should have done it a long time ago.
It came with cheapo bats, will I need to re-calibrate when they die? Will they die? OHH. I wonder how much they weigh? Grin
