Scientific Calculators & Converters
A full bench of physics and engineering converters: pressure, energy, power, force, torque, density, viscosity, flow, thermal and radiation units — all using standard SI definitions.
Frequently asked questions
What unit systems are supported?
SI (metric), imperial/US customary, and specialist units like atmospheres, BTU, calories, poise and rems — each tool lists every unit it supports.
Are these suitable for engineering work?
The conversion factors follow SI definitions and NIST reference values, but always verify critical engineering calculations against your project's required standard.
What's the difference between the scientific and basic converters?
Basic converters cover everyday units like meters and pounds; scientific converters cover derived and specialist units like pascals, joules, newtons and sieverts.
