Unit Converter Methodology

Normalized base model

Every unit has a conversion factor to a normalized base unit. Conversions pass through the base:

result = value × toBase(from) / toBase(to)

Example

180 cm to feet: toBase(cm) = 0.01, toBase(ft) = 0.3048. Result = 180 × 0.01 / 0.3048 = 5.91 ft.

Temperature — non-linear

Temperature uses offsets, not just ratios, so it has dedicated formulas:

• C = (F - 32) × 5/9
• F = C × 9/5 + 32
• K = C + 273.15

Exact factors

Conversion factors are exact by international agreement (e.g., 1 inch = 0.0254 meters exactly).
