[33] [37] Above 4 °C, however, thermal expansion becomes the dominant effect, [37] and water near the boiling point (100 °C) is about 4% less dense than water at 4 °C (39 °F). [ 36 ] [ f ] Under increasing pressure, ice undergoes a number of transitions to other polymorphs with higher density than liquid water, such as ice II , ice III ...
Density of pure water at 60 °F = / or / [8] Note: There is no universal agreement on the exact density of pure water at various temperatures since each industry will often use a different standard. For example the, USGS says it is 0.99907 g/cm 3 . [ 9 ]

The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
