swansont Posted May 28, 2019 Share Posted May 28, 2019 You can use calipers to measure (not calculate) a diameter Link to comment Share on other sites More sharing options...
beecee Posted May 28, 2019 Share Posted May 28, 2019 2 hours ago, Rook said: PLEASE HELP... thanks for any help. Depending on precision and tolerances, anything from a simple pair of outside calipers, to a microscope and up to Vernier calipers for greatest precision.

koti Posted May 28, 2019 Share Posted May 28, 2019 (edited) If its a regular rounded object like a sphere you just use simple math which you can find on the internet to find its measurements. If the object is round and not regular like an irregular blob of some sort, these days you use a 3D laser to measure its volume/surface...it has no diameter because its irregular. Maybe you mean volume not diameter ? Edited May 28, 2019 by koti Link to comment Share on other sites More sharing options...
DrP Posted May 29, 2019 Share Posted May 29, 2019 Micrometer? (small scale caliper as mentioned above). Link to comment Share on other sites More sharing options...
John Cuthber Posted May 29, 2019 Share Posted May 29, 2019 These days there's a reasonable chance that I'd take a picture of the object and a ruler at the same time (and at the same distance) and then measure the distances on the screen. Link to comment Share on other sites More sharing options...

How do u do that? Using smartphone camera, and some kind of 2D painting application.. Link to comment Share on other sites More sharing options...
