It is a customary unit.
The pound is NOT a metric unit.
Metric.
I'm guessing by customary, you mean imperial. if so inches are customary/imperial
Yes.
They use the metric system.
The customary units are ones we use everyday. metric units usually have the word meter on it. my teacher taught me meter metric no meter no metric.
They are the U.S. measurements. Instead of the Metric system that uses meters, the Customary system uses feet and inches.
600 millimeters in metric measurements is the equivalent of 23.622 inches in US customary measurements. One inch is the equivalent of 25.4 millimeters.
It is a customary unit.
Some similarities of the metric and customary systems
Metric tools are measured in millimeters and centimeters, while standard tools are measured in inches and fractions of an inch. This means that metric tools are used in countries that follow the metric system, while standard tools are used in countries that follow the imperial system. It is important to use the correct tool for measurements to ensure accuracy in construction and repair work.
Imperial measurements are based on multiples of various numbers eg 16 ozs in a pound, 14 pounds in a stone etc. Metric measurements are based on multiples of 10 eg 1000 grams in a kilogram etc. This makes Metric measurements easier to use in calculations.
The opposing systems are imperial and metric, not customary. But, meters are metric.
One US gallon of producer's milk (not skimmed, semi-skimmed, homogenised etc), weighs 10.1 pounds-force in customary measure and 44.5 newton in metric measure.
