Time conversion example
To find the Base per Custom relationship for a custom unit of BTU per day (Btu/d) and a base unit of BTU
per hour (Btu/h), input the following:
Custom Unit = Btu/d
Base Unit = Btu/h
Because:
1 d (Day) = 24 h (Hours)
Then:
1 Btu/d = ⫻ = 0.041667 Btu/h
1 Btu/d = 0.041667 Btu/h
Therefore:
Base per Custom = = = 0.041667
