Convert Kilogram-force metres to Gram-force millimetres
Convert Kilogram-force metres (kgf·m) to Gram-force millimetres (gf·mm) instantly and accurately.
Conversion Formula
gf·mm = kgf·m × 1000000
About Kilogram-force metres
The kilogram-force metre (kgf·m) equals exactly 9.80665 N·m, used in pre-SI European and legacy Asian engineering. Soviet/Russian GOST standards, early JIS turbine and compressor specifications, and older DIN automotive standards listed torque in kgf·m. A car wheel bolt at 10 kgf·m ≈ 98.1 N·m. 1 kgf·m = 9.80665 N·m = 100 kgf·cm ≈ 7.233 lbf·ft ≈ 86.80 lbf·in.
About Gram-force millimetres
The gram-force millimetre (gf·mm) equals 9.80665 × 10⁻⁶ N·m, the natural unit for precision micro-mechanisms. Swiss watchmaking datasheets list hairspring and balance-wheel detent torques in gf·mm; micro-servo holding torques, precision force gauge spring calibration, and miniature dental handpiece torque limits also fall in this range. A typical watch hairspring torque is 0.1-5 gf·mm. 1 gf·mm = 9.80665 × 10⁻⁶ N·m = 100 dyn·cm = 0.1 gf·cm.
