What this calculator does
Converts a measurement given in pound-force foots into pound-force inchs using the defined conversion factor.
What your result means
The same quantity expressed in lbf·in instead of lbf·ft. Nothing about the measurement itself changes.
Formula and working
lbf·in = lbf·ft × 12

10 lbf·ft = 120 lbf·in
Frequently asked questions
Symbols and assumptions
- lbf·ft
- Input unit — pound-force foot
- lbf·in
- Output unit — pound-force inch
- N·m
- Base unit used internally for torque
- • Both units measure torque, so the physical quantity is unchanged by the conversion.
- • The relationship is exactly linear: 1 lbf·ft = 12 lbf·in.
- • Values are converted through the SI base unit for this quantity rather than pair by pair.
Sources and review
Reviewed 2026-09-22 · Next review 2027-09-22
- • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
- • Displayed figures are rounded for readability; the full stored precision of the lbf·in value is used in every onward calculation.
