I am trying to localize my web application and I cannot manage to make Intl.NumberFormat work with electric units (ampere, ohm, volt, joule…).
In the documentation, they provide some examples and the list of units available.
Though I cannot manage to make it work with the electric units:
// Working
console.log(new Intl.NumberFormat('fr', { style: 'unit', unit: 'second' }).format(1000));
// Failing with Invalid unit argument for Intl.NumberFormat() 'volt'
console.log(new Intl.NumberFormat('fr', { style: 'unit', unit: 'volt' }).format(1000));Does someone have an idea why?

Answer
A subset of units from the full list was selected for use in ECMAScript.
Simple Unit ----------- acre bit byte celsius centimeter day degree fahrenheit fluid-ounce foot gallon gigabit gigabyte gram hectare hour inch kilobit kilobyte kilogram kilometer liter megabit megabyte meter mile mile-scandinavian milliliter millimeter millisecond minute month ounce percent petabyte pound second stone terabit terabyte week yard year
Pairs of simple units can be concatenated with “-per-” to make a compound unit. There is no default value; if the style is “unit”, the unit property must be provided.
Très cool: Megabytes per second becomes mégaoctets par seconde in French
console.log(
new Intl.NumberFormat('fr',
{ style: 'unit', unit: 'megabyte-per-second', 'unitDisplay': 'long' }
).format(1000)
);
