Diameter = 4.45 cm ===> Radius = 2.225 cm Height = 4.05 cm Volume = pi R2 H = pi x (2.225)2 x 4.05 = pi x (4.950625) x (4.05) = 62.90903 cm3 Density = 1000/Vol = 15.87578 gm/cm3 (rounded)
Grams and milligrams are fractions of a kilogram. A kilogram is the standard SI unit for mass
To calculate the mass of the platinum-iridium cylinder, we first need to determine its volume. The volume of a cylinder is calculated using the formula V = πr^2h, where r is the radius and h is the height. Given that the diameter is 39.0 mm, the radius is half of that, which is 19.5 mm. Converting the dimensions to meters (1 m = 1000 mm), we find the volume to be V = π(0.0195)^2(0.039) m^3. The density of platinum-iridium is approximately 21,550 kg/m^3, so the mass can be calculated by multiplying the volume by the density.
Gram or kilogram (= 1000 grams)
The standard International System of Units (SI) unit of mass is the kilogram (kg).
The mass of the earth is 5.9742 * 1024 kilograms.
The SI standard represented by an artifact is the International Prototype of the Kilogram (IPK), which is a platinum-iridium cylinder stored in France. It was used as the primary standard for the kilogram unit until the redefinition of the kilogram in terms of Planck's constant in 2019.
The mass of the cylinder of platinum-iridium kept in Paris is approximately 1 kilogram, as this is the standard kilogram prototype used as the international standard for mass. This is equivalent to around 2.2 pounds.
One kilogram (kg) is defined as the mass of a specific platinum-iridium alloy cylinder that is kept at the International Bureau of Weights and Measures in France. This cylinder is known as the International Prototype of the Kilogram (IPK) and serves as the reference standard for the kilogram unit.
The metric standard unit of mass is the kilogram (Kg).
The standard unit for measuring the mass of water, along with the mass of any other material, is a kilogram. And that is abbreviated as kg.
Kg (kilogram) is the standard - although it is not a standard of weight, but of mass. The kilogram is used world-wide as the standard of mass. It is part of the SI (the International System of units).
The standard diameter of a 16 screw is 0.1875 inches.
