Name of units should be their singular form. Eg. 'meter' instead of 'meters'. It's OK to say '5 meters', but it's completely wrong to call the unit of length of 'meters', because it's 'meter'.

BIPM is the International Bureau of Weights and Measures, an international standards organization established to maintain the International System of Units (SI). From BIPM's website - http://www.bipm.org/en/measurement-units/base-units.html - units are always on their singular form. Example: Unit: meter. Quantity: 5 meters. Unit: kilogram. Quantity 10 kilograms.

Some examples from the Unit and Measurements API:

* metersPerSecondSquared -> meterPerSecondSquared
* degrees -> degree
* arcMinutes -> arcMinute
* arcSeconds -> arcSecond
* radians -> radian

UnitAcceleration.gravity, for instance, uses the singular form (and correct).

Steps to Reproduce:
iOS 10 SDK, macOS Sierra SDK

Expected Results:
Unit names should be in their singular form.

Actual Results:
Most of them are on their plural form.
