Unit Consistency Checker

Verify that engineering equations are dimensionally consistent using dropdowns for common physical quantities

Unit Consistency Checker

Build the left-hand side and right-hand side of an equation from unit building blocks. Verify dimensional consistency.

Left-Hand Side (LHS)

LHS dimensions: [M·L·T^-2]

Right-Hand Side (RHS)

RHS dimensions: [M·L·T^-2]
✓
Dimensionally Consistent
LHS: [M·L·T^-2]  =  RHS: [M·L·T^-2]

Common Equation Examples

✓F = m·a (Newton)[N] = [kg·m/s²]
✓P = F/A (Pressure)[Pa] = [N/m²]
✓W = F·d (Work)[J] = [N·m]
✓P = W/t (Power)[W] = [J/s]
✓τ = r × F (Torque)[N·m] = [m·N]

How to Use This Calculator

1

Enter your input values
