Universal Unit Conversion Engine
Whether you are solving engineering calculations, translating metric specifications to US customary measurements, or verifying scientific temperatures, precision is critical. Rounding errors or approximation discrepancies can lead to costly mistakes in physics, software architecture, construction, and culinary recipes.

| Speed | Meter/sec (m/s) | Meter per second, kilometer per hour (km/h), mile per hour (mph), knot, foot per second |
Temperature Conversion Formulas
Unlike distance or weight where conversion relies purely on a multiplication ratio, temperature includes distinct zero-point offsets:
- Fahrenheit to Celsius: °C = (°F - 32) × 5/9
- Celsius to Fahrenheit: °F = (°C × 9/5) + 32
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Rankine: °R = K × 1.8
Frequently Asked Questions
What units can I convert with this tool?
You can convert across 8 core categories: Length (meters, feet, miles, etc.), Weight & Mass (kg, lbs, oz, grams), Temperature (°C, °F, K, °R), Area (acres, sq meters, sq feet), Volume (liters, gallons, cups, fl oz), Time (hours, days, milliseconds), Data Storage (MB, GB, GiB, TiB), and Speed (km/h, mph, m/s, knots).
How accurate are the conversion formulas?
All calculations strictly adhere to National Institute of Standards and Technology (NIST) constants and the International System of Units (SI). Conversions avoid loose decimal approximations, using exact ratio fractions and IEEE-754 precision safeguards.
Does the converter support negative values?
Yes. Negative numbers are fully supported where physically meaningful, such as sub-zero temperatures in Celsius and Fahrenheit.
What is the difference between Gigabyte (GB) and Gibibyte (GiB)?
Gigabyte (GB) is based on the decimal metric standard (1 GB = 1,000,000,000 bytes = 10^9), commonly used by storage hardware manufacturers. Gibibyte (GiB) is based on binary powers of two (1 GiB = 1,073,741,824 bytes = 2^30), commonly used by operating systems like Windows to report available RAM and disk space.
Does this unit converter work offline?
Yes. BrivTools' Unit Converter executes 100% locally in your browser with zero external server dependencies, meaning you can convert measurements without internet access once the page has loaded.
