In 1963, this definition was refined as the space occupied by 10 pounds of distilled water of density 0.998 859 g/mL weighed in air of density 0.001 217 g/mL against weights of density 8.136 g/mL (the original "brass" was refined as the densities of brass alloys vary depending on metallurgical composition), which was calculated as 4.546 091 879 ...

Avoirdupois ounce per fluid ounce (1 g/cm 3 ≈ 1.04317556 oz/US fl oz = 1.04317556 lb/US fl pint) Avoirdupois pound per cubic inch (1 g/cm 3 ≈ 0.036127292 lb/cu in) pound per cubic foot (1 g/cm 3 ≈ 62.427961 lb/cu ft) pound per cubic yard (1 g/cm 3 ≈ 1685.5549 lb/cu yd) pound per US liquid gallon (1 g/cm 3 ≈ 8.34540445 lb/US gal)
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 ...
The boiling point for each isomer is around 140 °C (284 °F). The density of each isomer is around 0.87 g/mL (7.3 lb/US gal; 8.7 lb/imp gal) and thus is less dense than water. The odor of xylene is detectable at concentrations as low as 0.08 to 3.7 ppm (parts of xylene per million parts of air) and can be tasted in water at 0.53 to 1.8 ppm.
It is equivalent to the units gram per millilitre (g/mL) and kilogram per litre (kg/L). The density of water is about 1 g/cm 3 , since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at 4 °C (39 °F).
The US fluid ounce is based on the US gallon, which in turn is based on the wine gallon of 231 cubic inches that was used in the United Kingdom prior to 1824. With the adoption of the international inch, the US fluid ounce became 1 ⁄ 128 gal × 231 in 3 /gal × (2.54 cm/in) 3 = 29.5735295625 mL exactly, or about 4% larger than the imperial unit.
2 O) equal to 0.999972 g/cm 3 (or 62.43 lb·ft −3). The ASBC table [8] in use today in North America, while it is derived from the original Plato table is for apparent relative density measurements at (20 °C/20 °C) on the IPTS-68 scale where the density of water is 0.9982071 g/cm 3.
