How specific heat capacity conversion works
Specific heat capacity is the energy needed to raise a unit mass by one unit of temperature. Values are normalized to Joule/kilogram/K before conversion to the requested output unit.
Values are converted to joule/kilogram/k first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Questions
Specific Heat Capacity FAQ
What is the reference unit for specific heat capacity conversions?
ConvertWin uses joule/kilogram/k (J/(kg·K)) as the internal reference for this category, then converts to the selected output unit.
How accurate is this specific heat capacity converter?
SI relationships follow the cited reference. Conventional and domain-specific factors use the established ConvertWin factor inventory; verify safety-critical work against the governing standard.
