One of the basics of general HVAC is simple unit conversion. We deal with BTUs, watts, volts, amps, Ah, Wh, °F, °C, CFM, kW, hp, EER, SEER, CEER ratings, and so forth. In most cases, these are either metric or US standard units; in some cases, we use formulas to convert from a specific rating to another specific rating.
This document provides useful conversions for units of length, area, volume, velocity, pressure, and sound level (dB to dB(A)) that are commonly used for ventilation calculations.
This document provides a guide with common unit conversions and engineering formulas for HVAC and refrigeration. It includes a table with popular unit conversions and sections on basic engineering practice, Ohm's law, resistor combinations, power equations, pump and fan horsepower calculations, and density and pressure conversions.
