Examples: USA, UK and the majority of their current or ancient colonies.
America uses the customary units f measurement.
All of them. Whatever units a country uses are 'customary' in that country.
No, only the United States uses the customary units, the rest of the world and science uses metrics [so it will be a good idea to brush up on it]
Every country uses the system of measurement that's 'standard' in that country. The 'Metric System' is standard for every country in the world, except three of them. Liberia, Myanmar, and the USA use pounds, inches, and gallons, innocently referred to as the 'customary' system.
Customary units
United States, Liberia, Burma.
Metric and customary systems are both systems of measurement used to quantify physical quantities such as length, weight, and volume. They both have units for common measurements like meters for length and kilograms for weight. However, they differ in the specific units used and their conversion factors.
Use whatever is common in your country. In the long term, however, the entire world should switch to metric, for reasons of standardization, so if you happen to live in a country that uses non-metric units, you might try to push for metrification.
Myanmar formerly known as Burma uses the imperial system of measurement. It used to be a British colony and has not yet adopted the metric system.
Only if you live in a country which uses obsolete measurement i=units (US). In the developed world, the appropriate unit is a centimetre.
The US is one of the 3 remaining countries that still use Imperial (old British) units to measure distance. They therefore uses feet, inches and miles. The rest of the world uses the international standard decimal units relating to the Metre.
Turkey uses the Metric System.The only country that does not use the Metric System is the USA.
