How to convert 1 zeptogram (zg) = 0.001 attogram (ag).
Zeptogram (zg) is a unit of Weight used in Metric system.
Attogram (ag) is a unit of Weight used in Metric system. Zeptograms: A Unit of Weight
Zeptograms are a unit of weight that are used for measuring extremely small masses, such as atoms, molecules, and particles. Zeptograms are also known as quadrillionths of a gram. The symbol for zeptogram is zg.
Definition of the Zeptogram
The zeptogram is defined as one quadrillionth of a gram, which is the base unit of mass in the International System of Units (SI). The zeptogram is also equal to one thousandth of an attogram or one millionth of a femtogram.
The zeptogram is equal to about 2.2×1024 pounds or 1.54×1020 grains. The zeptogram is also equal to about 6.02×1026 atomic mass units or 1.66×1036 kilograms.
How to Convert Zeptograms
Zeptograms can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert zeptograms to other units of weight in the US customary system and the SI system:
 To convert zeptograms to pounds, multiply by 2.2×1024. For example, 10 zg = 10 x 2.2×1024 = 2.2×1023 lb.
 To convert zeptograms to grains, multiply by 1.54×1020. For example, 5 zg = 5 x 1.54×1020 = 7.7×1020 gr.
 To convert zeptograms to tonnes, multiply by 1×1024. For example, 20 zg = 20 x 1×1024 = 2×1023 t.
 To convert zeptograms to kilograms, multiply by 1×1021. For example, 15 zg = 15 x 1×1021 = 1.5×1020 kg.
 To convert zeptograms to grams, multiply by 1×1018. For example, 25 zg = 25 x 1×1018 = 2.5×1017 g.
 To convert zeptograms to milligrams, multiply by 0.000000000000001. For example, 30 zg = 30 x 0.000000000000001 = 0.00000003 mg.
Where Zeptograms are Used
Zeptograms are used in different countries and regions for different applications and purposes. Here are some examples of where zeptograms are used:
 In the fields of physics, chemistry, and microbiology, zeptograms are used for measuring weight, especially for atoms, molecules, and particles.
 In the fields of medicine and pharmacology, zeptograms are used for measuring weight, especially for drugs, hormones, and biomarkers.
 In the fields of biotechnology and nanotechnology, zeptograms are used for measuring weight, especially for nanostructures, nanomaterials, and nanodevices.
 In the fields of environmental science and toxicology, zeptograms are used for measuring weight, especially for pollutants, contaminants, and toxins.
History of Zeptograms
Zeptograms have a relatively recent history that dates back to the late 20th century. Here are some highlights of the history of zeptograms:
 The zeptogram 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 zeptogram 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 zeptogram 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 zeptogram was also referred to as the quadrillionth of a gram or the millipico gram in some countries and contexts to emphasize its extremely small size.
Example Conversions of Zeptograms to Other Units
Here are some examples of conversions of zeptograms to other units of weight:
 1 zg = 2.2×1024 lb
 1 zg = 1.54×1020 gr
 1 zg = 1×1024 t
 1 zg = 1×1021 kg
 1 zg = 1×1018 g
 1 zg = 0.000000000000001 mg
 1 zg = 1.66×1036 kN
 1 zg = 3.53×1026 oz
Zeptograms also can be marked as Zeptogrammes (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.
