How to Convert SEER to EER or COP KW/TON HSPF

How to convert SEER to EER

EER  = SEER*.875 *Simplified **
EER  = -.02*SEER2 + 1.12*SEER *Detailed
  **Multiplier of .875 varies by Climate  

How to convert EER to COP to KW/TON

 Starting with KW/TON
EER  = 12/(KW/Ton)
COP  = 12/3.413/(KW/TON)
 = 3.516/(KW/TON)

 Starting with EER
KW/TON  = 12/EER
COP  = EER/3.413

 Starting with COP
EER  = COP*3.413
KW/TON  = 12/COP/3.413
 = 3.516/COP

How to convert HSPF to COP

COP  = HSPF*.293 *Simplified**
COP  = -.026*HSPF2 + 0.624*HSPF *Detailed
  **Multiplier of .293 varies by Climate
