Convert common HVAC units of measurement.
Project & Input Data
Conversion type
no.
Engineering Assumptions
Direct calculation — Exact unit conversion
- The conversions are fixed exact factors (kW, TR, BTU/h, L/s, m³/h, CFM, Pa, inWG, °C, °F) and depend on no project criterion.
- All percentages and inputs are user-defined; the calculation is purely arithmetic and assumes no particular code or specification.
Formula Summary
- 1 TR = 3.5168 kW, 1 kW = 3412.14163 BTU/h
- 1 m³/h = L/s × 3.6, 1 CFM = L/s × 2.11888
- 1 Pa = 0.00401463 inWG
- °F = °C × 9/5 + 32
