How Does This Calculator Work?
The calculator multiplies pad length × width × thickness (converted from inches to feet) to get cubic feet, then divides by 27 to convert to cubic yards.
Small equipment pads — for an AC condenser, generator, shed, or hot tub — are a common DIY concrete project. This calculator gives you the cubic yards needed for your specific pad dimensions.
Example Calculation
AC Pad Example
A 4 ft × 3 ft pad, 4 inches thick.
(4×3×(4/12))/27 ≈ 0.148 cubic yards.
