Enter the total power consumption (watts) and the total temperature differential (C) into the Radiator Performance Calculator. The calculator will evaluate the Radiator Performance. 

Radiator Performance Formula

The following two example problems outline the steps and information needed to calculate the Radiator Performance.

RP = P / (TD/10)


  • RP is the Radiator Performance (Watts/10-C)
  • P is the total power consumption (watts) 
  • TD is the total temperature differential (C) 

How to Calculate Radiator Performance?

The following steps outline how to calculate the Radiator Performance.

  1. First, determine the total power consumption (watts). 
  2. Next, determine the total temperature differential (C). 
  3. Next, gather the formula from above = RP = P / (TD/10).
  4. Finally, calculate the Radiator Performance.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total power consumption (watts) = 300

total temperature differential (C) = 20

RP = P / (TD/10) = ?
