Enthalpy conversion btu/lb to kj/kg
Can someone explain the conversion of enthalpy from btu/lb to kj/kg?
Every website I search says to multiply by 2.326, but when I do some checks (using web based calculator or psychrometric charts) the results do not work.
77F, 50%RH = 29.3 btu/lb
25C (i.e. 77F) 50%RH= 50.29 kj/kg
and 29.3 x 2.326 <> 50.29!
I am using an Alerton system which has an Enthalpy block which only supports F and btu/lb and I am working in SI (metric) units.
