Javascript - Conversor de unidades de medida científicas

Septiembre 2017

Aquí un conversor de unidades de medida científicas que funciona sólo con javascript y en ámbito local en el navegador, sin recurrir al código del servidor. Con el conversor podemos convertir cualquier unidad (o combinación) a cualquier otra unidad rápidamente:

// new units can be added at the end of the list

// if 2 units have the same [number], le first one is ignored

// if 2 units have the same symbol, the second one is ignored

// fundamental SI units : meter, kilogram, second, Ampere, Kelvin, mol, candela

// ex: hr = time = s =>  m^0.kg^0.s^1.A^0.K^0.mol^0.cd^0

// ex: g = acceleration = m / s^2 =>  m^1.kg^0.s^-2.A^0.K^0.mol^0.cd^0

// ex: V = tension = kg.m²/s³/A =>  m^2.kg^1.s^-3.A^-1.K^0.mol^0.cd^0
