How Unit Conversion Works
Most conversions use a fixed conversion factor: multiply the input by the ratio of the two units’ sizes relative to a shared base unit. Temperature is the exception — it uses offset formulas (°C × 9/5 + 32 = °F) instead of simple multiplication.
Metric vs Imperial
The metric system (SI) scales by powers of ten, making arithmetic straightforward: 1 km = 1,000 m, 1 g = 1,000 mg. The imperial system (used mainly in the US) has less regular relationships — 1 mile = 5,280 feet, 1 pound = 16 ounces. Use this converter to bridge both systems instantly.
Tips for Accurate Conversions
- US and UK pints differ (473 mL vs 568 mL) — always check which is intended.
- Scientific notation (e.g.
1.5e6) is accepted as input. - Digital storage uses binary prefixes here (1 KB = 1,024 B), matching OS file size reporting.
- For very large or very small values, check the full-precision result to avoid rounding loss.
