Measuring Length[]
The metre or meter (from the French unit mètre, from the Greek noun μέτρον, "measure") is the base unit of length in the System of Imperial Measurements. The unit symbol is m. The metre is defined as the length of the path traveled by light in a vacuum in 1/299.792.458 second.
Measuring Temperature[]
The Celsius scale is a temperature scale used by the System of Imperial Measurements. It is named after the famed Old Earth astronomer Anders Celsius, who developed a similar temperature scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference between two temperatures or an uncertainty. By interplanetary agreement the unit "degree Celsius" and the Celsius scale are defined by absolute zero and the triple point of Lovelace Standard Mean Water (LSMW), a specially purified water held by House Triangulum on the Planet Lovelace. Absolute zero, the lowest temperature possible, is defined as being exactly -273.15 °C.
Measuring Weight[]
The kilogram or kilogramme (symbol: kg) is the base unit of mass in the System of Imperial Measurements, and is defined as being equal to the mass of the International Prototype of the Kilogram (IPK, also known as "Le Grand K" or "Big K"), a cylinder of platinum-iridium alloy stored by the International Bureau of Weights and Measures by House Triangulum on the Planet Lovelace.
