How to Convert Ounce-inch to Kilonewton-meter
- 1 ozf·in = 0.000007061551814 kN·m
- 1 kN·m = 141611.9327 ozf·in
- Example: convert 15 ozf·in to kN·m: 15 ozf·in = 15 × 0.000007061551814 kN·m = 0.0001059232772 kN·m
Formula
kN·m = ozf·in × 0.000007061551814226
or kN·m = ozf·in ÷ 141611.9326612
Derivation from SI units:
- 1 ozf·in = 1/16 lbf·in = 0.00706155181 N·m
- 1 kN·m = 10³ N·m
- 1 ozf·in = 0.007061551814226 N·m ÷ 1000 N·m per kN·m = 0.000007061551814226 kN·m
Both units are defined exactly, so the factor is exact. Ounce-inch definition: ounce-inch; Kilonewton-meter definition: kilonewton-meter.
Worked examples
- A reading of 10 ozf·in converts to 0.00007061551814 kN·m.
10 ozf·in × 0.000007061551814 = 0.00007061551814 kN·m - A value of 100 ozf·in is 0.0007061551814 kN·m.
100 ozf·in × 0.000007061551814 = 0.0007061551814 kN·m
