About these measurements
Specific heat capacity is heat capacity per unit mass.
The base reference used here is the joule per kilogram kelvin. One it btu per pound fahrenheit is 4,186.8 base units; one kilojoule per kilogram kelvin is 1,000 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.
Common questions
How do I convert BTU IT/(lb·°F) to kJ/(kg·K)?
