Metric measurements use powers of 10.
Any other system has NO bases or logic.
logical answers are all basic math
They are the U.S. measurements. Instead of the Metric system that uses meters, the Customary system uses feet and inches.
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.
In most of the world, there is no difference, because the metric system is the customary system.In a few isolated hold-out corners of the world, such as the USA, the English system is still customary.In those places, the main difference between the metric system and their customary system is that theircustomary system is a lot harder for their people to learn than the metric system would be.
It is a customary unit.
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.
Some similarities of the metric and customary systems
The opposing systems are imperial and metric, not customary. But, meters are metric.
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.
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.
The pound is NOT a metric unit.
