Error Propagation (Mul/Div)

See how relative errors add when quantities are multiplied or divided.

Run simulation

Key Notes

01

For R = AB or A/B: ΔR/R = ΔA/A + ΔB/B (relative errors add).

02

For R = Aⁿ: ΔR/R = n·ΔA/A.

Formulas

Product/quotient

Relative errors add.

Power

Relative error scales with exponent.

Important Points

Always use relative error for products/quotients.
