About Unit Converter
Our comprehensive Unit Converter handles conversions between metric and imperial systems across 10 categories. Length: mm, cm, m, km, inches, feet, yards, miles, nautical miles. Key conversions: 1 inch = 2.54 cm, 1 foot = 30.48 cm, 1 mile = 1.609 km. Weight/Mass: mg, g, kg, metric ton, ounce, pound, stone. 1 kg = 2.20462 lbs, 1 lb = 0.453592 kg. Temperature: Celsius, Fahrenheit, Kelvin with formulas °F = (°C × 9/5) + 32, °C = (°F - 32) × 5/9. Area: sq m, sq ft, acres, hectares. Volume: mL, L, tsp, tbsp, fl oz, cups, pints, quarts, gallons (US and UK). Speed: km/h, mph, m/s, knots. Time: seconds, minutes, hours, days, weeks, years. Digital storage: bits, bytes, KB, MB, GB, TB, KiB, MiB, GiB, TiB (supports both decimal and binary prefixes). Energy/Power: Joules, calories, watt-hours, kWh, BTU, horsepower. Pressure: Pascal, kPa, bar, PSI, atm, torr. Features include precision control (0-6 decimal places), swap button to reverse units, and recent conversions history.
Unit Converter is optimized for fast browser-based use, so you can test multiple scenarios in seconds.
Formula & Logic
- 01Linear conversions: converted = value × (from_factor ÷ to_factor).
- 02Temperature: °F = (°C × 9/5) + 32, °C = (°F - 32) × 5/9, K = °C + 273.15.
- 03Volume conversions account for US customary vs Imperial (UK) differences.
- 04Fuel economy: L/100km = 235.215 ÷ mpg (US).
- 05Binary prefixes (KiB, MiB) use factor 1024, decimal prefixes use factor 1000.
Practical Examples
- 01Baseline check: Use realistic inputs in Unit Converter to generate a first-pass estimate.
- 02Sensitivity check: Change one key input at a time to compare how the output shifts.
- 03Decision check: Save two or more scenarios and use the differences to choose the better option.
Important Limitations
- •Results depend on the accuracy of your inputs.
- •Displayed values may be rounded for readability.
- •Edge cases can vary based on locale standards, conventions, or input formatting.
