Frequently asked questions

How accurate are the results?

Calculations use SI and official conversion factors (e.g. 1 inch = 25.4 mm, 1 pound = 0.45359237 kg), rounding only for display to at most 6 significant digits. Temperature uses the proper formulas (°F = °C × 9/5 + 32, K = °C + 273.15) rather than a simple multiplier.

Are Korean units like pyeong and don supported?

Yes. Pyeong for area (1 pyeong = 400/121 m² ≈ 3.3058 m²), plus don (1 don = 3.75 g) and geun (1 geun = 600 g) for weight — handy for converting real-estate areas and precious-metal weights.

What's the difference between KB and KiB?

A kilobyte (KB) is 1,000 bytes; a kibibyte (KiB) is 1,024 bytes. Storage manufacturers mostly use decimal units (KB, MB, GB) while operating systems and programs often use binary units (KiB, MiB, GiB), which is why the same file can appear to have different sizes.

What kind of unit is the knot?

The knot (kn) is a speed unit used by ships and aircraft: 1 knot is one nautical mile (1,852 m) per hour, or about 0.5144 m/s.
