Initial Data

As π multiple:

Tip: When input unit is radians, enter values as numbers or pi expressions, for example 2.5, 1/3, pi/2, or 1/3pi. Type pi directly in the field.

Fuel units: Consumption units are directional: L/100km means lower is better, while mpg and km/L mean higher is better.

Temperature: The converter applies exact temperature formulas (not simple multiplication). Absolute zero limits are enforced.

Data units: SI data units use base 10 (kB = 1,000 bytes; MB = 1,000,000 bytes), while IEC binary units use base 2 (KiB = 1,024 bytes; MiB = 1,048,576 bytes).

Pressure reference: Common references: 1 atm = 101325 Pa and 1 bar ≈ 14.5038 psi.

Time units: Month and year conversions are based on average lengths, not calendar-specific month/day boundaries.

Mass concentration units: Use this converter for mass concentration units such as g/L, mg/L, ppm, and ppb.
