Heat Density Converter
Convert between 5 heat density units.
About Heat Density
Heat density is energy delivered per unit of area — a total, not a rate. Solar and climate work use the langley, one calorie per square centimetre, which is why it sits here beside the SI joule per square metre. One langley is 41,840 J/m². A clear summer day can deliver several hundred of them.
