Lol. Not really. A set of calibers is nice to have, but certainly not required. I honestly don't think I know anyone who actually measures. We all just eyeball our placement. It's like everything else... Pretty subjective.please don't tell me it requires another tool..
yep I think I got a head of myself I'm going back to just a single build.Keep at it. You'll get it. You might be better served though, just learning for one. Instead of jumping around trying to build for multiple devices, maybe just stick with one of them. Once you get that down, then move into other ones. As you know, each one is a little different, but the principals are the same.
For example, I can build the same coil for an APO, kayfun, and a Kanger head. All of them can be built identical, however, all have different reading do to placement, configuration, and leg length. The kanger heads are always higher because the leg length is the longest. The Kayfun is then a bit lower because the legs are a touch shorter. Then with the APO it's again just a touch off due to leg length depending on how I place it, or can be halved by utilizing dual coils. yep going back to just a single build.
Even though I built all identical coils, same wraps, same ID, same awg wire, variance will happen across devices. Because of these subtle variances, it can become frustrating getting things to work how you want.

That was my original thought, but all read the same on ohm meter, multi meter, and, 2 other devices with resistance checkers built in. Never full ohm off or anything like that, just subtle point 1 to point 3 off. I determined it to be the leg length. Rational how I came to that was by removing the coil from kanger heads, and placing in rda. Shortened legs brought me where I wanted to be. Longer legs increased the numbers ever so slightly.Sounds like the ohm meter acting up to me.
1 ohm was my target! Now the easy part.
