What is the measuring in the metric system for lengthmassand volume Starting with the largest unit?

Answer 1

The standard units are:

Length: meter

mass: kilogram

volume: cubic meter

SI prefixes are commonly used for larger and smaller units; for example, kilo for thousand, Mega for million, Giga for billion, etc.; and for smaller units: milli for a thousandth, micro for a millionth, etc. - but note the following:

• For meter, it is not common to use prefixes above "kilo". "megameter" is technically correct, but seldom used. The use of smaller prefixes (milli, micro, nano, etc.), on the other hand, is quite common.
• For square or cubic units, the prefix is applied before squaring or cubing. Thus, a "cubic millimeter" is a (1/1000 meter)3, and as a result of the cubing, a cubic meter has a billion cubic millimeters.
• For mass, and due to historical reasons, the base unit already has the "kilo" prefix. Here, too, "mega" and larger prefixes are not common, but smaller prefixes are commonly used. In this case, the prefix is applied to gram: milligram, microgram.
