What is a good capacity conversion factor from steam capacity to hot water at 180 deg (70 deg room air) for cast iron radiators?
I have 0.9 which seems high.

  Don't forget that the numbers above represent average water temp and not entering water temp.
  https://heatinghelp.com/systems-help-center/conversion-factors/ has the full range.

  150 BTUH per EDR (ft2 rating) @ Average 170F temp (180 supply and 160 return).
