Jun 18, 2001 #8 Guest In the UK we have gone through this conversion thing already, so here is typical conversions used Power kW -> BTU/hr(x 3412) Tons Refrigeration -> kW (x 3.517) Intensity of heat flow rate BTU/hr square foot -> W/square metre (x 3.155) Typically for budget cooling load estimating we use 140 W/square metre.
