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 2.2×10-21 pounds or 1.54×10-17 grains. The attogram is also equal to about 6.02×10-23 atomic mass units or 1.66×10-33 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 2.2×10-21. For example, 10 ag = 10 x 2.2×10-21 = 2.2×10-20 lb.
• To convert attograms to grains, multiply by 1.54×10-17. For example, 5 ag = 5 x 1.54×10-17 = 7.7×10-17 gr.
• To convert attograms to tonnes, multiply by 1×10-21. For example, 20 ag = 20 x 1×10-21 = 2×10-20 t.
• To convert attograms to kilograms, multiply by 1×10-18. For example, 15 ag = 15 x 1×10-18 = 1.5×10-17 kg.
• To convert attograms to grams, multiply by 1×10-15. For example, 25 ag = 25 x 1×10-15 = 2.5×10-14 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 decimal-based 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 = 2.2×10-21 lb
• 1 ag = 1.54×10-17 gr
• 1 ag = 1×10-21 t
• 1 ag = 1×10-18 kg
• 1 ag = 1×10-15 g
• 1 ag = 0.000000000001 mg
• 1 ag = 6.02×10-23 u
• 1 ag = 1.66×10-33 kN
• 1 ag = 3.53×10-23 oz

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.

Definition of the Milligram

The milligram is defined as one one-thousandth of a gram, which is one one-millionth of a kilogram, which is the base unit of mass in the SI. The kilogram is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 ×10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the meter and the second are defined in terms of c and ∆ν Cs. The Planck constant is a fundamental physical constant that relates the energy of a photon to its frequency.

The milligram is a very small unit of weight, equivalent to about 0.000035 ounces or 0.000002 pounds. It is commonly used for measuring small masses, such as medicines, chemicals, vitamins, minerals and microorganisms.

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.

Where Milligrams are Used

Milligrams are used in different countries and regions for different applications and purposes. Here are some examples of where milligrams are used:

History of Milligrams

Milligrams have a long history that dates back to ancient times. Here are some highlights of the history of milligrams:

• The milligram was originally based on the weight of a grain of wheat or barley, which was used as a unit of mass in ancient civilizations such as Egypt, Mesopotamia and Greece.
• The milligram was part of the gram-centimeter-second system of units (CGS) that was developed in the 19th century as an alternative to the meter-kilogram-second system of units (MKS).
• The milligram was replaced by the kilogram as the base unit of mass in the SI system that was adopted in 1960 as an international standard for measurements.
• The milligram was redefined in terms of the kilogram and the Planck constant in 2019 as part of a major revision of the SI system.
