How to Convert Pound-foot to Ounce-inch
- 1 lbf·ft = 192 ozf·in
- 1 ozf·in = 0.005208333333 lbf·ft
- Example: convert 15 lbf·ft to ozf·in: 15 lbf·ft = 15 × 192 ozf·in = 2880 ozf·in
Formula
ozf·in = lbf·ft × 192
Derivation from SI units:
- 1 lbf·ft = 4.4482216152605 N × 0.3048 m = 1.3558179483314 N·m
- 1 ozf·in = 1/16 lbf·in = 0.00706155181 N·m
- 1 lbf·ft = 1.355817948331 N·m ÷ 0.007061551814226 N·m per ozf·in = 192 ozf·in
Both units are defined exactly, so the factor is exact. Pound-foot definition: pound-foot; Ounce-inch definition: ounce-inch.
Worked examples
- A reading of 30 lbf·ft converts to 5760 ozf·in.
30 lbf·ft × 192 = 5760 ozf·in - A value of 200 lbf·ft is 38400 ozf·in.
200 lbf·ft × 192 = 38400 ozf·in
