Conversion Formulas

Mathematical principles behind unit conversions

V_{target} = V_{input} \times \frac{F_{input}}{F_{target}}

$V_{target}$ = Value in target unit

$V_{input}$ = Value in input unit

$F_{input}$ = Conversion factor to base

$F_{target}$ = Conversion factor from base

°F = °C \times \frac{9}{5} + 32

Special offset formula for temperature scales

P = \max(0, 6 - \lfloor\log_{10}(|V|)\rfloor)

$P$ = Decimal places for optimal precision

Understanding Units

Metric (SI) system uses base-10 scaling, while Imperial system has historical origins. Most countries use metric, but US primarily uses Imperial.

Modern units are defined by fundamental physical constants, ensuring accuracy and reproducibility worldwide.

Conversion accuracy depends on the original measurement precision and the conversion factors used.

The International System of Units (SI) is maintained by the International Bureau of Weights and Measures (BIPM).
