HVAC Heat Load Calculator

Estimates the heating or cooling load for a room or building in BTU/hr based on floor area, ceiling height, insulation quality, temperature difference, and window area. Use it to size furnaces, air conditioners, and heat pumps.

Floor Area (sq ft)

Ceiling Height (ft)

Insulation Level

Temperature Difference (°F)

Window Area (sq ft)

Beam Deflection Calculator

Calculate the maximum deflection of a simply supported beam under a point load, uniformly distributed load (UDL), or end load using standard Euler-Bernoulli beam theory. Use it to size beams in structural design or to verify deflection stays within serviceability limits (typically L/250 or L/360).
