Handy numbers
| 1 ton of cooling | 12,000 BTU/h ≈ 3.517 kW |
| 1 kW | 3,412 BTU/h |
| 1 psi | 6.895 kPa ≈ 27.7 in. w.c. |
| 1 in. w.c. | 249 Pa |
| 1 CFM | 0.472 L/s ≈ 1.699 m³/h |
| 1 lb of refrigerant | 16 oz ≈ 454 g |
Pressure conversions are gauge-to-gauge or absolute-to-absolute; to go from psig to psia, add about 14.7.
