Algunos factores de conversión.

LONGITUD.
1m = 100cm = 1,000mm
1m = 3.281ft = 39.37in
1km = 1,000m
1pulg = 2.540cm
1pie = 12pulg = 30.48cm
1yd = 3pie = 91.44cm =914.4cm
1mi = 5280ft = 1.609km = 1,609m
1 milla náutica = 1.151mi = 6,076pie = 1,852m
1 vara (española) = 0.836m

ÁREA.
1m² = 10⁴cm² = 10.76pie²
1pulg² = 6.452cm²
1pie² = 144pulg²
1 milla cuadrada = 2.788×10^7 pie² = 640 acres
1 acre = 43,560pie²
1 hectárea = 10⁴m² = 2.471 acres
1 manzana = 10,000 varas cuadradas = 6,988.96m² = 0.698896ha

VOLUMEN.
1 litro = 1,000cm³ = 61.02pulg³
1pie³ = 28.32 litros = 7.477 galones
1 galón = 3.788 litros
1m³ = 1,000 litros

MASA.
1kg = 10³g
1 tonelada métrica = 1,000kg

DENSIDAD.
1g/cm³ = 1,000kg/m³ = 1kg/L

FUERZA.
1N = 10⁵ dinas = 0.2248lb
1lb = 4.448N = 4.448×10⁵ dinas.
1lb = 16 onzas
1 ton = 2,000lb
1lb = 453.6g

TIEMPO.
1 año = 365.25 días
1 día = 86,400s
1h = 3,600s
1min = 60s

RAPIDEZ.
1m/s = 3.281pie/s
1km/h = 0.2778m/s = 0.6214mi/h
1mi/h = 1.466pie/s = 0.4470m/s = 1.609km/h
1 nudo (knot) = 1 milla náutica/h

PRESIÓN.
1Pa = 1N/m² = 1.450×10^-4 lb/pulg² = 0.209lb/pie²
1bar = 10⁵Pa
1lb/pulg² = 6,895Pa
1atm = 1.013×10⁵Pa = 1.013bar = 14.7lb/pulg²
1mm Hg = 1torr = 133.3Pa

ENERGÍA, TRABAJO, CALOR.
1Btu = 252.0cal = 1,055J = 777.9pie•lb
1cal = 4.186J
1kWh = 3.600×10⁶J

POTENCIA.
1kW = 10³ W = 1.431hp
1hp = 550pie•lb/s =745.7W
1 watt = 1J/s
