Conversion definitions
Length uses international inch, foot, yard and mile. Mass uses avoirdupois oz/lb (16 oz = 1 lb) and metric tonne t (1000 kg). Signed length/mass values are allowed as arithmetic. Temperature is an absolute reading, not a difference: K = °C + 273.15 = (°F + 459.67) × 5/9. Values below 0 K are rejected. Unit symbols are language independent.
Inputs use exact decimal arithmetic. At most 60 digits including 30 fractional digits; results show up to 12 decimals. ≈ means rounded. ASCII and the selected language's digits are accepted. No implicit separator conversion.
