HVAC & Sheet Metal Calculator

HVAC & Sheet Metal Calculator is a comprehensive construction math tool designed as a Chrome extension for HVAC pros and sheet metal specialists. It handles ductwork offsets and angle measurements, and streamlines dimensional math with built-in sheet metal functions, trig, and imperial/metric conversions for fast, accurate field work.

The tool offers sheet metal capabilities (X, Y, R; polar-rectangular conversions; S-bend offsets; centerline radius and arc length; air-flow analysis) alongside trig and HVAC-specific calculations (CFM, RPM, SP, BHP; velocity and velocity pressure). It also covers construction math such as area/volume, stairs layout, angle determinations, and more, with context-sensitive help and a proven engine to boost accuracy and productivity.
