Why does specific heat has the same numerical value in metric and british systems?
Specific heat is dimensionless, and dimensionless units have the same value in any system. Specific heat is the ratio between two densities - that of the substance considered, and that of water. The ratio of two quantities of the same dimension will naturally be a dimensionless number.
What are dimensionless numbers?
the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.
