Length, weight, temperature, area, volume, data size, time conversion
Real-world unit conversion isn't just length and weight — you'll also need temperature (with its non-linear scales), area, volume, data sizes (with the binary vs decimal trap), and time. This converter covers all seven categories in one place.
Type a value once, see all related units instantly. Fully client-side: the math is simple enough that there's no reason to round-trip to a server.

1.0737 GB (decimal)Temperature scales aren't proportional — they have offsets. °F = °C × 9/5 + 32, K = °C + 273.15. Rounding shows up faster than for length or weight. We round to a few decimal places for readability; full precision is internal.
GB (gigabyte) = 10^9 bytes (decimal, used by storage manufacturers and most network speeds). GiB (gibibyte) = 2^30 bytes ≈ 1.074 × 10^9 bytes (binary, used by RAM, file systems on Linux/macOS, Windows misnaming as 'GB'). The 7% gap is why your '1 TB' drive shows up as ~931 GB.
Mostly different. A US gallon (3.785 L) is smaller than a UK / Imperial gallon (4.546 L). Pint, fluid ounce, and bushel similarly differ. This tool labels them explicitly when both exist.
Currency rates change minute to minute and need a live data source — incompatible with our 'works fully offline, no server' principle. Use a dedicated currency tool with a live rate feed.
Internally we use double-precision floats — about 15-17 significant decimal digits. Display is rounded for readability. For scientific or engineering work that needs exact decimal precision, use a dedicated tool — JS floats have well-known precision quirks (0.1 + 0.2 ≠ 0.3 exactly).
