How it works

The input is normalised to the normalization unit (m/s²) using fixed NIST SP 811 conversion factors, then converted to the target unit. Same-unit conversions return the input exactly.

Assumptions & limits

  • Metric and inch/foot factors and standard gravity (9.80665 m/s²) are defined values; binary floating-point storage may round them.
  • Calculations use JavaScript double-precision floating-point arithmetic, which can introduce small rounding errors; display formatting may round further.

Verified runs

Synthetic examples executed at build revision 24533ff on . Cards round decimal results to 6 significant figures; matching uses full precision and the tolerance below. Matches cover the displayed fields, not every possible input or clinical or engineering validation.

  • Inputs: Value: 1 g; From unit: g; To unit: m/s²

    Result: Value: 9.80665 m/s² (expected Value: 9.80665 m/s²) ✓

  • Inputs: Value: 0 g; From unit: g; To unit: m/s²

    Result: Value: 0 m/s² (expected Value: 0 m/s²) ✓

  • Inputs: Value: 1 ft/s²; From unit: ft/s²; To unit: m/s²

    Result: Value: 0.3048 m/s² (expected Value: 0.3048 m/s²) ✓

How these runs were checked

Method: acceleration-linear@1.0.1. Expectations come from the listed test fixtures or hand arithmetic; they are not copied from these executions. Omitted optional inputs use the method defaults. Run dates record execution, not expert review or fresh measurements.

Reproduce from the source checkout with pnpm --filter @sumivo/web gen:verified-runs. A rebuild changes execution times; the revision identifies its Git starting point, including any uncommitted changes made for that build.

FAQ

Why convert through a base unit?
Normalising every unit to m/s² first means one small, checkable factor table covers every from/to pair with floating-point rounding possible.
