Gram (G) Sainmhíniú aonaid
The gram originally refferred to as the gramme is a unit of mass & weight in the International System of Units (SI) equal to one one thousandth of a kilogram (kg). The gram is represented by the symbol g.
Originally defined in 1795 as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a meter (1 cm3), and at the temperature of melting ice. The defining temperature (~0 °C) was later changed to 4 °C, the temperature of the maximum density of water.
However, by the late 19th century, there was an effort to make the base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a gram as one one-thousandth of a kilogram (one gram is 1×10−3 kg). The kilogram, as of 2019, is defined by the International Bureau of Weights and Measures from the fixed numerical value of the Planck constant (h).
