The kilogram is the only standard unit to include an SI prefix (kilo-) as part of its name. The gram (10 −3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram , rather than on kilogram ; thus 10 3 kg is a megagram (10 6 g), not a * kilokilogram .
Kilogram' means 'one thousand grams' [2] and is colloquially abbreviated to kilo. [ 3 ] The kilogram is an SI base unit , defined ultimately in terms of three defining constants of the SI, namely a specific transition frequency of the caesium-133 atom, the speed of light , and the Planck constant .
The equivalent SI measure is the nanogram per second per square meter per pascal. [citation needed] 1 ng·s −1 ·m −2 ·Pa −1: ... 1 kg·s −1 ·m −2 ·Pa −1:

The term combines the SI prefix nano-indicating a 1 billionth submultiple of an SI unit (e.g. nanogram, nanometre, etc.) and second, the primary unit of time in the SI. A nanosecond is to one second, as one second is to approximately 31.69 years. A nanosecond is equal to 1000 picoseconds or 1 / 1000 microsecond.
For example, the median lethal dose (LD-50) for ingested polonium-210 is 240 μCi; about 53.5 nanograms. The typical human body contains roughly 0.1 μCi (14 mg) of naturally occurring potassium-40. A human body containing 16 kg (35 lb) of carbon (see Composition of the human body) would also have about 24 nanograms or 0.1 μCi of carbon-14 ...
Tygart said, and expert witnesses summoned by Valieva’s team conceded, that the 2.1 nanograms were “actually very consistent with the tail end of an excretion,” if a full dose of TMZ had ...
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
