Nm to ft-lb Converter

Convert torque between N·m and ft·lbf bidirectionally with common reference values.

Torque conversion studio

N·m → ft·lbf, with the reverse path always visible

Start with N·m and see ft·lbf immediately, or edit any of four torque units. Control precision, inspect tolerance ranges, convert mixed-unit lists, save recent conversions, and verify the definition-derived factor before using a setting.

Batch summary

4 rows ready to convert.

Rows are conversions only. A value that resembles a common fastener setting is not a recommendation. For critical tightening work, use the manufacturer’s specification and an appropriate calibrated tool.

Definition-derived conversion basis

The torque factor comes from the pound-force and foot definitions, not from a rounded lookup table. Cross-check the published factors in the NIST Guide to the SI torque table.

1 lbf = 4.4482216152605 N
1 ft = 0.3048 m
1 ft·lbf = 4.4482216152605 × 0.3048 = 1.3558179483314 N·m

Primary: 1 N·m = 0.737562149277 ft·lbf.
Small-torque bridge: 1 ft·lbf = 12 in·lbf exactly.
Legacy metric-force bridge: 1 kgf·m = 9.80665 N·m.
Mental estimate: N·m × 3/4 ≈ ft·lbf, useful only as a rough check.

Torque vs energy: N·m and J share dimensions, and “foot-pound” is also used in energy contexts, but this page treats the values strictly as torque. The physical quantity and use case matter.

Do not turn a conversion chart into a torque specification. Fastener torque depends on the actual manufacturer/service specification and application conditions.
