Frequently Asked Questions
The unit converter supports 9 categories: length (millimetres to light-years), weight/mass (milligrams to metric tonnes), temperature (Celsius, Fahrenheit, Kelvin, Rankine), area (square millimetres to square miles), volume (millilitres to cubic metres and gallons), speed (metres per second to knots and light speed), time (milliseconds to years), digital storage (bits to petabytes), and pressure (pascals to atmospheres and psi).
All conversions use precise factor-based mathematics derived from official SI definitions. Results are calculated with up to 8 significant figures of precision and rounded only for display. For everyday use, the accuracy is equivalent to professional scientific calculators.
Yes — select the Temperature category, set From to Fahrenheit and To to Celsius, then enter your value. The formula used is °C = (°F − 32) × 5/9. For example, 98.6°F = 37°C. You can also convert to Kelvin (K = °C + 273.15) or Rankine from the same screen.
Fluid ounces (fl oz) measure volume and are used for liquids — for example, a can of soda contains 12 fl oz. Ounces (oz) measure weight or mass. The two units are in different categories: fluid ounces are under Volume and ounces are under Weight. One fluid ounce of water weighs approximately 1.043 ounces, but this varies by the density of the liquid being measured.
You can enter standard decimal numbers and the tool will handle very large or very small values correctly. Results for very large or very small conversions are displayed in standard decimal form where practical. For values in scientific notation, enter the equivalent decimal value (e.g. enter 0.000001 for 1×10⁻⁶).
Over 200 units across 9 categories: length, weight, temperature, area, volume, speed, time, digital storage, and pressure.
Temperature uses offset-based formulas (°F = °C × 9/5 + 32), not simple multiplication factors. It requires special conversion logic.
Yes — all unit conversions work without internet. Only the currency converter requires a connection to fetch live rates.
Multiply meters by 3.28084. For example, 5 meters = 5 × 3.28084 = 16.4042 feet. Select Length category and set From: Meter, To: Foot.
