Measurement Standards & Frequently Asked Questions

Learn how scientific conversion factors, binary data units, and temperature scales work.

Decimal vs. Binary Data Storage

Decimal units (KB, MB, GB, TB) use powers of 10 (1 KB = 1,000 Bytes), as used by hard drive makers and networking standards. Binary units (KiB, MiB, GiB, TiB) use powers of 2 (1 KiB = 1,024 Bytes), matching operating system memory and RAM calculations.

Temperature Scales & Absolute Zero

Temperature conversions use offset formulas rather than simple multiplication. Absolute zero (0 K, -273.15 °C, -459.67 °F) is the lowest theoretical temperature where molecular motion ceases; values below absolute zero are rejected.

Internal Full Precision

All arithmetic calculations maintain full floating-point precision internally through standardized base units before user precision rounding is applied, eliminating compounding conversion errors.
