Example calculation
1 in = 25.4 mm; 1 L = 0.001 m³; 0 °C = 32 °F = 273.15 K.
Calculation method
y = ax + b; 1 in = 25.4 mm; °F = °C × 9/5 + 32; K = °C + 273.15
Calculation limits
Temperature conversion applies to temperature values, not temperature differences. hp denotes mechanical horsepower, not metric PS. Conversion does not improve measurement accuracy.
