How to convert1 microgram (mcg) = 1000000000 femtogram (fg). Microgram (mcg) is a unit of Weight used in Metric system. Femtogram (fg) is a unit of Weight used in Metric system. Micrograms: A Unit of WeightDefinition of MicrogramsA microgram is a unit of mass or weight equal to onemillionth of a gram. It is part of the metric system, which is based on powers of ten. The symbol for microgram is μg according to the International System of Units (SI); the recommended symbol in the United States and United Kingdom when communicating medical information is mcg. One microgram is equivalent to 0.001 milligrams or 0.000000001 kilograms. It is also equal to 0.000015 grains, which is a unit of weight in the imperial system. How to Convert MicrogramsTo convert micrograms to other units of weight, we need to multiply or divide by the appropriate conversion factor. For example, to convert micrograms to milligrams, we divide by 1000; to convert micrograms to grams, we divide by 1,000,000; and to convert micrograms to kilograms, we divide by 1,000,000,000. Here are some examples of conversion factors for different units of weight:
Where Micrograms are UsedMicrograms are very commonly used in scientific and medical fields where precision and accuracy are essential. For example, micrograms may be used to measure:
Micrograms may also be used in different countries for different applications. For example, in China, micrograms are used to measure the weight of silk; in India, micrograms are used to measure the weight of spices; and in Switzerland, micrograms are used to measure the weight of gold. History of MicrogramsThe origin of micrograms can be traced back to the development of the metric system in France in the late 18th century. The metric system was designed to simplify and standardize the measurement of length, area, volume and mass by using decimal units based on the meter and the kilogram. The gram was defined as onethousandth of a kilogram, and the microgram was defined as onemillionth of a gram. The metric system was adopted by many countries around the world over the next two centuries, but it also faced some resistance and opposition from those who preferred the traditional units of measurement. In some cases, the metric system was modified or adapted to suit local needs and preferences. For example, in Germany, the metric system was officially adopted in 1872, but some old units such as pfund (pound) and zentner (hundredweight) are still used today. The International System of Units (SI) was established in 1960 as a modern version of the metric system that is based on seven base units: meter, kilogram, second, ampere, kelvin, mole and candela. The SI also defines several derived units that are combinations of the base units, such as newton, joule and watt. The SI is recognized as the global standard for measurement and is used by most countries and international organizations today.

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:
