Formula

F = m × a (Newton's Second Law). Force in Newtons equals mass in kilograms multiplied by acceleration in m/s².

Calculate voltage, current, resistance, or power using Ohm's Law (V = I × R). Enter any two values to find the others.

Calculate voltage drop in electrical wiring based on wire gauge, length, current, and material. Ensure your circuits meet NEC recommendations.

Calculate density, mass, or volume using the formula ρ = m/V. Includes a reference table of common material densities.
