How to convert1 femtogram (fg) = 1E18 kilogram (kg). Femtogram (fg) is a unit of Weight used in Metric system. Kilogram (kg) is a unit of Weight used in Metric system. Femtograms: A Unit of WeightFemtograms are a unit of weight that are used for measuring extremely small masses, such as atoms, molecules, and particles. Femtograms are also known as trillionths of a gram. The symbol for femtogram is fg. Definition of the FemtogramThe femtogram is defined as one trillionth of a gram, which is the base unit of mass in the International System of Units (SI). The femtogram is also equal to one thousandth of a picogram or one millionth of a nanogram. The femtogram is equal to about 2.2×1018 pounds or 1.54×1014 grains. The femtogram is also equal to about 6.02×1020 atomic mass units or 1.66×1030 kilograms. How to Convert FemtogramsFemtograms can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert femtograms to other units of weight in the US customary system and the SI system:

Kilograms: A Unit of WeightDefinition of the KilogramA kilogram is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to the mass of the International Prototype of the Kilogram (IPK), a cylinder of platinumiridium alloy stored at the International Bureau of Weights and Measures in France. One kilogram can also be written as kg or 1000 g. History of the KilogramThe kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water at 4 °C, which was determined to be 18841 grains. In 1799, the Kilogramme des Archives, a platinum artifact, replaced it as the standard of weight. In 1889, the IPK became the new standard of the unit of weight for the metric system and remained so for 130 years, until the current definition was adopted in 2019. The kilogram, as well as other metric units of weight, such as the gram and the tonne, were introduced in the 19th century as part of the decimal system of measurement that aimed to simplify and unify the units used in science and commerce. The kilogram was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units. How to Convert KilogramsTo convert kilograms to other units of weight, we need to use conversion factors that relate the kilogram to the desired unit. For example, to convert kilograms to pounds, we need to know that one pound is equal to 0.45359237 kg. Therefore, one kilogram is equal to 2.2046226218 pounds. Here are some common conversion factors for kilograms:
To convert from other units of weight to kilograms, we need to use the inverse of these conversion factors. For example, to convert pounds to kilograms, we need to divide by 2.2046226218. Where Kilograms are UsedThe kilogram is a unit of weight that is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals. For example, an adult human body has an average weight of about 62 kg. The kilogram is also used to measure the weight of some physical quantities such as force, pressure and torque. For example, one newton (N) is equal to one kilogram times one meter per second squared (kg x m/s^{2}). Example Conversions of Kilograms to Other UnitsHere are some examples of how to convert kilograms to other units of weight using the conversion factors given above:
ConclusionThe kilogram is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity.
