Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.

The hyl is a unit of mass equal to 1 kgf⋅m −1 ⋅s 2 (9.806 65 kg). The poncelet (p) is a unit of power equal to 1 kgf ⋅m⋅s −1 ( 980.665 W ). The technical atmosphere (at) is a (non-coherent) unit of pressure equal to 1 kgf ⋅cm −2 ( 98 066 .5 Pa ).
For instance, K20, the US's primary standard, originally had an official mass of 1 kg − 39 μg (micrograms) in 1889; that is to say, K20 was 39 μg less than the IPK. A verification performed in 1948 showed a mass of 1 kg − 19 μg. The latest verification performed in 1989 shows a mass precisely identical to its original 1889 value.
Weight is the force exerted on a body by a gravitational field, and hence its weight depends on the strength of the gravitational field. Weight of a 1 kg mass at the Earth's surface is m × g; mass times the acceleration due to gravity, which is 9.81 newtons at the Earth's surface and is about 3.5 newtons at the surface of Mars. Since the ...
Costner departed from “Yellowstone” after Season 5 Part 1, which aired in the fall of 2022. He announced the news in a video posted on social media, saying, “After this long year-and-a-half ...
1793: The grave (the precursor of the kilogram) was defined as the mass of 1 litre (dm 3) of water, which was determined to be 18841 grains. [11] 1795: the gram (1 / 1000 of a kilogram) was provisionally defined as the mass of one cubic centimetre of water at the melting point of ice. [12] 1799: The Kilogramme des Archives was manufactured as a ...
