Metrology Bench’s calibration toolbox
A free, open-source collection of browser-based calculators for calibration work, from RTD conversions and pressure units to uncertainty budgets and decision rules.
- For
- Calibration technicians and metrology practitioners
- Worth noticing
- Calculators refuse inputs outside an equation’s stated range and include versioned formulas, coefficients, sources, and checkable test vectors.
Field notes
The toolbox spans temperature and pressure conversions, local gravity and liquid-head corrections, deadweight testers, mass and air-buoyancy calculations, and calibration decision rules. Its reference material includes test vectors, and the page links to taxonomy, standards, and changelog sections. The project identifies Custom Calibration in North Haven, Connecticut, as its maintainer; it also cautions that results are calculated values, not certified results.
