       It's... Bigger than i thought it would be.About time I had one of these. Quite the upgrade from my old clicky thing that doesn't go low enough for small screws on PCBs etc

       @xabean This one is specced for 1.7 - 17.7 lbf-in or 2-20 kg-cm torque (it reads lower but isnt calibrated outside that range) and was $369. If you want the NIST traceable or 17025 calibration certificate that's an extra $100 or 200 respectively.Eventually I want the full set, they have a low range model that does 0.45 - 4.42 lbf-in or 0.5-5 kg-cm, as well as a high range that does 3-35 lbf-in or 4-40 kg-cm.The low end would be nice to have at some point but I figured this would be a good starter model for "nice torque drivers".

       @azonenberg TIL, that this type of device exists. Ah well… 💸

       @azonenberg @xabean it never really clicked for me that lbf-feet is measuring "weight" not force until I saw the kg-cm.. poundfeet are something I read sometimes and always ignored so I never thought about that.Screeches in #si, #metric, and #physics

       @RichiH @xabean it's force-distance so technically should be kgf-cm. 1 kgf is the force exerted by a 1kg mass under 1 g acceleration, trivially convertible to newtons

       @RichiH @xabean similarly 1 lb = mass, 1 lbf = force

       @azonenberg @xabean ah, thanks! Now I know what the f stands for.That means kgf-cm is just Nm, written weirdly.I can see how this might be more familiar to people growing up with lbf-feet though I would personally optimize for global readability. NB: not a criticism.

       @RichiH @xabean I think the datasheet had Nm as well I just didnt feel like doing all the conversions, most of the connectors I work with are US-market and thus the datasheet specs are in lbf-in so that's what I'm used to

       @RichiH @xabean Casually in the US it's common for people to conflate pounds mass and pounds force, but in more technical contexts people do (usually) use the right units

       @azonenberg @xabean yeah, it seems easy to confuse the two. I saw the "f" and it didn't click.FWIW, I did the math, kgf-cm are the literal same as Nm, so you can use either

       @azonenberg @xabean (it was not a lot of math)

       @RichiH @xabean isn't there a factor of 9.8 in there somewhere?

       @azonenberg @xabean yes, but it's one way in the kg, and the other way in the f, so it equals out.
