Using locale settings to detect wheter to use imperial units

Question

I\'m working on an app that wants to display lengths either in centimeters (cm) or in inches(\"). Is there a way to select the right unit from the locale? In any event I\'m also

Answer 1

A more or less complete way to do this is this way.

Kotlin:

private fun Locale.toUnitSystem() =
    when (country.toUpperCase()) {
        // https://en.wikipedia.org/wiki/United_States_customary_units
        // https://en.wikipedia.org/wiki/Imperial_units
        "US" -> UnitSystem.IMPERIAL_US
        // UK, Myanmar, Liberia, 
        "GB", "MM", "LR" -> UnitSystem.IMPERIAL
        else -> UnitSystem.METRIC
    }

Note that there is a difference between UK and US imperial systems, see the wiki articles for more details.
