Pound-foot to Newton-meter (Pound-foot to Newton-meter)
Result
1.355817948 Newton-meter
Formula
Newton-meter = Pound-foot × 1.355817948
1 Pound-foot = 1.355817948 Newton-meter, and 1 Newton-meter = 0.7375621493 Pound-foot.
Fuel economy is converted through the US gallon (3.785411784 L) and imperial gallon (4.54609 L): L/100 km = 235.215 ÷ mpg (US). Power uses mechanical horsepower and metric horsepower (PS = 735.49875 W). Torque uses 1 lb·ft = 1.3558179 N·m.
Worked examples
- 1 Pound-foot × 1.355817948 = 1.3558179 Newton-meter
- 10 Pound-foot × 1.355817948 = 13.558179 Newton-meter
- 100 Pound-foot × 1.355817948 = 135.58179 Newton-meter
Common mistakes
- L/100 km is inverse to mpg — lower is better — so it does not scale linearly: going from 10 to 20 mpg saves far more fuel than going from 40 to 50.
- UK and US mpg differ because the imperial gallon is 20% larger: 40 mpg (UK) is 33.3 mpg (US).
- Car makers in Europe and Japan usually quote PS, not horsepower; 100 PS is 98.6 hp.
