How to convert 1 milligram (mg) = 1E+12 attogram (ag).
Milligram (mg) is a unit of Weight used in Metric system.
Attogram (ag) is a unit of Weight used in Metric system. Milligrams: A Unit of Weight
Milligrams are a unit of weight that are used in the International System of Units (SI), also known as the metric system. Milligrams are derived from the Latin word mille, which means thousand, and the French word gramme, which means weight. The symbol for milligram is mg.
How to Convert Milligrams
Milligrams can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert milligrams to other units of weight in the US customary system and the SI system:
 To convert milligrams to ounces, divide by 28349.523125. For example, 1000 mg = 1000 / 28349.523125 = 0.035 oz.
 To convert milligrams to pounds, divide by 453592.37. For example, 5000 mg = 5000 / 453592.37 = 0.011 lb.
 To convert milligrams to tons (short), divide by 907184740. For example, 10000 mg = 10000 / 907184740 = 0.000011 ton.
 To convert milligrams to grams, divide by 1000. For example, 2000 mg = 2000 / 1000 = 2 g.
 To convert milligrams to kilograms, divide by 1000000. For example, 3000 mg = 3000 / 1000000 = 0.003 kg.
 To convert milligrams to micrograms, multiply by 1000. For example, 50 mg = 50 x 1000 = 50000 µg.
Milligrams also can be marked as Milligrammes (alternative British English spelling in UK). Attograms: A Unit of Weight
Attograms are a unit of weight that are used for measuring extremely small masses, such as atoms, molecules, and particles. Attograms are also known as trillionths of a gram. The symbol for attogram is ag.
Definition of the Attogram
The attogram is defined as one trillionth of a gram, which is the base unit of mass in the International System of Units (SI). The attogram is also equal to one thousandth of a femtogram or one millionth of a picogram.
The attogram is equal to about 2.2×1021 pounds or 1.54×1017 grains. The attogram is also equal to about 6.02×1023 atomic mass units or 1.66×1033 kilograms.
How to Convert Attograms
Attograms can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert attograms to other units of weight in the US customary system and the SI system:
 To convert attograms to pounds, multiply by 2.2×1021. For example, 10 ag = 10 x 2.2×1021 = 2.2×1020 lb.
 To convert attograms to grains, multiply by 1.54×1017. For example, 5 ag = 5 x 1.54×1017 = 7.7×1017 gr.
 To convert attograms to tonnes, multiply by 1×1021. For example, 20 ag = 20 x 1×1021 = 2×1020 t.
 To convert attograms to kilograms, multiply by 1×1018. For example, 15 ag = 15 x 1×1018 = 1.5×1017 kg.
 To convert attograms to grams, multiply by 1×1015. For example, 25 ag = 25 x 1×1015 = 2.5×1014 g.
 To convert attograms to milligrams, multiply by 0.000000000001. For example, 30 ag = 30 x 0.000000000001 = 0.00000003 mg.
Where Attograms are Used
Attograms are used in different countries and regions for different applications and purposes. Here are some examples of where attograms are used:
 In the fields of physics, chemistry, and microbiology, attograms are used for measuring weight, especially for atoms, molecules, and particles.
 In the fields of medicine and pharmacology, attograms are used for measuring weight, especially for drugs, hormones, and biomarkers.
 In the fields of biotechnology and nanotechnology, attograms are used for measuring weight, especially for nanostructures, nanomaterials, and nanodevices.
 In the fields of environmental science and toxicology, attograms are used for measuring weight, especially for pollutants, contaminants, and toxins.
History of Attograms
Attograms have a relatively recent history that dates back to the late 20th century. Here are some highlights of the history of attograms:
 The attogram was derived from the gram, which was originally defined as the mass of one cubic centimeter of water at its maximum density of four degrees Celsius in the late 18th century.
 The attogram was part of the metric system that was introduced in France in the late 18th century as a decimalbased system of measurement that was designed to replace the traditional units that varied from region to region.
 The attogram was adopted by many countries around the world as part of the International System of Units (SI) that was established in the mid 20th century as a universal system of measurement that was based on seven base units and several derived units.
 The attogram was also referred to as the trillionth of a gram or the millinano gram in some countries and contexts to emphasize its extremely small size.
Example Conversions of Attograms to Other Units
Here are some examples of conversions of attograms to other units of weight:
 1 ag = 2.2×1021 lb
 1 ag = 1.54×1017 gr
 1 ag = 1×1021 t
 1 ag = 1×1018 kg
 1 ag = 1×1015 g
 1 ag = 0.000000000001 mg
 1 ag = 6.02×1023 u
 1 ag = 1.66×1033 kN
 1 ag = 3.53×1023 oz
Attograms also can be marked as Attogrammes (alternative British English spelling in UK).
