The maximum density of water at 4℃ is 1000kg/m3, which is determined by mass = density× volume; It is known that one ton of water =1000kg =1000l =1m3.

Density is a measure of mass in a specific volume, which can be expressed by the symbol ρ. Standard density (also called "reference density") refers to the density of a substance or mixture of substances at a certain temperature or pressure.

This can better compare different density values. The standard maximum dry density refers to the dry density of soil or other road building materials under the optimal water content according to the standard compaction test method.

Mass refers to the size of the substance contained in an object. The quality units used in ancient China are: stone, jun, gold and beam; There are units of mass in the English system, such as pounds, ounces, blue and grains.

Conversion between unit of volume

The unit conversion formula of a cube is 1 m3 = 1000 cubic decimeter, 1 cubic decimeter = 1000 cubic centimeter, 1 cubic centimeter = 1000 cubic millimeter. When we calculate the volume of liquid, we can also use liters or milliliters. The conversion formula between them is: 1 liter = 1 cubic decimeter = 1000 ml = 1000 cubic centimeter.

The conversion rate between two adjacent unit of volume is 1000. Commonly used unit of volume are: cubic meter, cubic decimeter, cubic centimeter, etc. Volumes are generally calculated in unit of volume, such as liters and milliliters, but unit of volume is sometimes used.

Conversion between unit of volume: 1 m3 = 1000 liter = 1000 cubic decimeter = 10000000 ml = 1000000 cubic centimeter = 1 000000 cubic millimeter,/.
