How to Convert Ounce-inch to Pound-foot
- 1 ozf·in = 0.005208333333 lbf·ft
- 1 lbf·ft = 192 ozf·in
- Example: convert 15 ozf·in to lbf·ft: 15 ozf·in = 15 × 0.005208333333 lbf·ft = 0.078125 lbf·ft
Formula
lbf·ft = ozf·in ÷ 192
Derivation from SI units:
- 1 ozf·in = 1/16 lbf·in = 0.00706155181 N·m
- 1 lbf·ft = 4.4482216152605 N × 0.3048 m = 1.3558179483314 N·m
- 1 ozf·in = 0.007061551814226 N·m ÷ 1.355817948331 N·m per lbf·ft = 0.005208333333333 lbf·ft
Both units are defined exactly, so the factor is exact. Ounce-inch definition: ounce-inch; Pound-foot definition: pound-foot.
Worked examples
- A reading of 10 ozf·in converts to 0.05208333333 lbf·ft.
10 ozf·in × 0.005208333333 = 0.05208333333 lbf·ft - A value of 100 ozf·in is 0.5208333333 lbf·ft.
100 ozf·in × 0.005208333333 = 0.5208333333 lbf·ft
