About these measurements
Torque describes a force’s turning effect around an axis.
The base reference used here is the newton meter. One pound force foot is 1.355817948 base units; one newton meter is 1 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
