The conversion rule

Foot-pounds = newton-meters × 0.7375621493. The factor is exact, derived from 1 lbf = 4.4482216 N and 1 ft = 0.3048 m (whose product, 1.3558179, is the reverse factor).

Two-step mental check: knock 25 % off the N·m value, then nudge down slightly — 200 N·m → ~150 → 147.5 ft·lb exact.

Chart values worth memorizing

20 N·m = 14.75 ft·lb (small fasteners). 50 N·m = 36.88 ft·lb. 100 N·m = 73.76 ft·lb (the anchor value). 135 N·m = 99.57 ft·lb — almost exactly 100, a handy landmark.

Every row in the table below is computed from the exact factor, not copied from a rounded chart.

Questions, answered

Frequently asked

Is this the same as newton meters to foot pounds? +
Yes — “newtons to ft lbs” colloquially drops the meter. The conversion is N·m → ft·lb.
What's 300 N·m in ft lbs? +
300 × 0.7375621 = 221.27 ft·lb.
Why do printed charts disagree slightly? +
Rounding. Charts using 0.7376 or 0.74 drift from the exact 0.7375621493 — trivial at 20 N·m, noticeable at 600.
