Unit Efciency Ratings EER is the industry standard in the United States for rating the ef ciency of a commercial unit. On some international speci ciations, however, miimum ef ciencies are often listed in COP or KW/TON. To convert our ef ciency ratings from EER to COP or KW/TON, you can use the following table: EER COP KW/TON 9.0 2.64 1.33 10.0 2.93 1.20 11.0 3.22 1.09 12.0 3.52 1.00 13.0 3.81 0.92 14.0 4.10 0.86 Example for a unit with a net capacity of 100 MBH and a total power requirement of 10 KW: EER = 100 MBH = 10.0 MBH 10KW KW COP (100 MBH 10 KW) = 2.93 (Note: 3.415 MBH = 1 KW) 3.415 MBH/KW KW/TON = 10 KW x 12 MBH/TON 1.20 KW/TON (Note: 12 MBH = 1 TON) 100 MBH Temperature Conversion Fahrenheit and Centigrade To convert Fahrenheit to Celsius (Centigrade) .556 x (F - 32) = C To convert Celsius (Centigrade) to Fahrenheit (C x 1.8) + 32 = F C F C F -30 -22 40 104 -25 -13 45 113 -20 -4 50 122 -15 5 55 131 -10 14 60 140 -5 23 65 149 0 32 70 158 5 41 75 167 10 50 80 176 15 59 85 185 20 68 90 194 25 77 95 203 30 86 100 212 35 95 105 221 APPROX.
