The formula
Each unit is defined by how it relates to one second (the base unit). A value is first converted to the base unit, then to the target unit:
result = ( value × from-factor + from-offset − to-offset ) ÷ to-factor
For simple units the offset is zero, so it reduces to value × from-factor ÷ to-factor. The offset term is what makes temperature scales (which don't share a zero point) convert correctly.
Worked example
Convert 2 h to min: choose h as From and min as To, enter 2, and the answer appears immediately with a rounded and a full-precision figure.
Frequently asked questions
- Are these time conversion factors exact?
- Yes. The factors are the internationally standardised definitions (for example 1 inch = 0.0254 m exactly), not rounded approximations.
- Does my data leave my device?
- No. The calculation runs entirely in your browser with JavaScript — nothing is sent to a server.
- Why show two figures?
- The headline is the full-precision result; the “Rounded” figure is a friendlier 2-decimal version for everyday use.
