Pound-feet to Newton-meters Converter
1 pound-foot ≈ 1.35581795 newton-meters
1 pound-foot equals 1.35582 newton-meters
How to convert pound-feet to newton-meters
Pound-foot and pound-inch here use pound-force. Although torque and energy share dimensions, torque describes a turning effect; these values do not become energy values without an angular displacement.
N·m = lbf·ft × 1.355817948One pound-foot is 1.355817948 newton-meters, so a single multiplication converts any value.
13.5582 N·m ≈ 10 × 1.355817948Pound-feet to newton-meters conversion table

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
