The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]
The density of solid clay bricks is around 2000 kg/m 3: this is reduced by frogging, hollow bricks, and so on, but aerated autoclaved concrete, even as a solid brick, can have densities in the range of 450–850 kg/m 3. Bricks may also be classified as solid (less than 25% perforations by volume, although the brick may be "frogged," having ...
— "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum .
ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm (0.079–0.248 in) for fine and 20–63 mm (0.79–2.48 in) for coarse. One cubic metre of gravel typically weighs about 1,800 kg (4,000 lb), or one cubic yard weighs about 3,000 lb (1,400 kg). Gravel is an important commercial product, with a number of applications.
Densities using the following metric units all have exactly the same numerical value, one thousandth of the value in (kg/m 3). Liquid water has a density of about 1 kg/dm 3, making any of these SI units numerically convenient to use as most solids and liquids have densities between 0.1 and 20 kg/dm 3. kilogram per cubic decimetre (kg/dm 3)
the medium gross density of 850 kg/m 3 to 1.100 kg/m 3 (white coloured blocks, suitable for standard usage) the high gross density blocks of 1.100 kg/m 3 to 1.500 kg/m 3 (reddish colour, suitable for walls with higher acoustic performance requirements) The dimensions of these blocks are: length 500 mm, height 500 mm. Four blocks thus make 1 m 2.
Instead the formula that would fit some of the Bonales data is k ≈ 2.0526 - 0.0176TC and not k = -0.0176 + 2.0526T as they say on page S615 and also the values they posted for Alexiades and Solomon do not fit the other formula that they posted on table 1 on page S611 and the formula that would fit over there is k = 2.18 - 0.01365TC and not k ...
The volumetric heat capacity can also be expressed as the specific heat capacity (heat capacity per unit of mass, in J⋅K −1 ⋅kg −1) times the density of the substance (in kg/L, or g/mL). [1] It is defined to serve as an intensive property.
