Calculators

Calculates the pitch diameter of a metric screw thread, given its nominal diameter and pitch.

Calculates the total R-value of insulation materials based on their individual R-values and thicknesses.

Calculates the number of floor joists needed and their total cost, based on room dimensions, joist spacing, and the cost per joist.

Calculates the required airflow in cubic feet per minute (CFM) for a room based on its dimensions and desired air changes per hour.
