Formula model
Base-unit conversion
Metric and imperial distance constants are exact for common units such as inch, foot, yard, and mile.
base = amount * factor + offset
result = (base - targetOffset) / targetFactor
result = (base - targetOffset) / targetFactor
Scope
Fixed conversions first
Currency, crypto, and market-rate conversions need live exchange data, so they are kept separate from the fixed scientific units in this build.
Exact units
Lengths, masses, storage, time, and most derived units.
Offset units
