Conversion factors are defined relative to the displayed base unit. Input precision limits meaningful output precision; this does not change a physical quantity or perform a safety assessment.

Formula

y = x × a ÷ b

x is the input, y is the converted value, a is the source-unit factor and b is the target-unit factor. Use the factors in the table below.

Scope and limitations

Conversion factors are defined relative to the displayed base unit. Input precision limits meaningful output precision; this does not change a physical quantity or perform a safety assessment.

Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.

Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
