About Unit Converter

Unit Converter is a free, fast, and privacy-friendly tool that converts values between measurement units across 57 categories — from everyday units like length and temperature to specialised categories like magnetism, radiation, and thermal conductivity.

What We Cover

Our converter spans ten groups of measurement categories:

• Common — Length, Temperature, Area, Volume, Weight, Time, Speed, Pressure, Energy, Power, Force, Angle
• Data & Digital — Data Storage, Data Transfer, Image Resolution
• Mechanics — Density, Specific Volume, Acceleration, Angular Velocity, Angular Acceleration, Torque, Moment of Inertia, Flow Rate, Mass Flow Rate
• Fluids — Dynamic Viscosity, Kinematic Viscosity, Surface Tension, Molar Concentration
• Heat — Thermal Conductivity, Specific Heat Capacity, Heat Flux Density, Thermal Resistance
• Electricity — Current, Potential, Resistance, Resistivity, Conductance, Capacitance, Inductance, Charge
• Magnetism — Magnetic Flux, Flux Density, Field Strength, Magnetomotive Force
• Light — Frequency, Illumination, Luminance, Luminous Intensity
• Radiology — Radiation Activity, Radiation Exposure, Absorbed Dose & Dose Equivalent
• Other — Fuel Economy, SI Prefixes, Dry Volume, Lumber Volume, Typography, Sound

Our Principles

• No tracking. We collect no personal data and set no tracking cookies. Two localStorage keys store your theme preference and recent category history — nothing else, and it never leaves your device.
• Accurate conversion factors. All factors are sourced from NIST, SI, and international standards. Results are provided for educational and reference purposes.
• Works offline. After your first visit, the app is cached and available without an internet connection.
• Accessible. Built with keyboard navigation, screen reader labels, sufficient colour contrast, and respect for reduced-motion preferences.
• Free forever. No paywalls, no accounts, no premium tiers.

Accuracy Disclaimer

Conversion results are for reference and educational purposes only. While we strive for accuracy using internationally recognised standards, floating-point rounding may affect results for very large or very small values. For safety-critical applications — engineering, medicine, pharmaceuticals, aerospace — always verify results with a certified reference source or professional.
