How to convert

1 picogram (pg) = 1E-12 gram (g). Picogram (pg) is a unit of Weight used in Metric system. Gram (g) is a unit of Weight used in Metric system.

Picograms: A Unit of Weight

Picograms are a unit of weight that are used for measuring extremely small masses, such as atoms, molecules, and particles. Picograms are also known as billionths of a gram. The symbol for picogram is pg.

Definition of the Picogram

The picogram is defined as one billionth of a gram, which is the base unit of mass in the International System of Units (SI). The picogram is also equal to one thousandth of a nanogram or one millionth of a microgram.

The picogram is equal to about 2.2×10-15 pounds or 1.54×10-11 grains. The picogram is also equal to about 6.02×10-17 atomic mass units or 1.66×10-27 kilograms.

How to Convert Picograms

Picograms can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert picograms to other units of weight in the US customary system and the SI system:

• To convert picograms to pounds, multiply by 2.2×10-15. For example, 10 pg = 10 x 2.2×10-15 = 2.2×10-14 lb.
• To convert picograms to grains, multiply by 1.54×10-11. For example, 5 pg = 5 x 1.54×10-11 = 7.7×10-11 gr.
• To convert picograms to tonnes, multiply by 1×10-15. For example, 20 pg = 20 x 1×10-15 = 2×10-14 t.
• To convert picograms to kilograms, multiply by 1×10-12. For example, 15 pg = 15 x 1×10-12 = 1.5×10-11 kg.
• To convert picograms to grams, multiply by 1×10-9. For example, 25 pg = 25 x 1×10-9 = 2.5×10-8 g.
• To convert picograms to milligrams, multiply by 0.000001. For example, 30 pg = 30 x 0.000001 = 0.00003 mg.

Where Picograms are Used

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

• In the fields of physics, chemistry, and microbiology, picograms are used for measuring weight, especially for atoms, molecules, and particles.
• In the fields of medicine and pharmacology, picograms are used for measuring weight, especially for drugs, hormones, and biomarkers.
• In the fields of biotechnology and nanotechnology, picograms are used for measuring weight, especially for nanostructures, nanomaterials, and nanodevices.
• In the fields of environmental science and toxicology, picograms are used for measuring weight, especially for pollutants, contaminants, and toxins.

History of Picograms

Picograms have a relatively recent history that dates back to the late 20th century. Here are some highlights of the history of picograms:

• The picogram 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 picogram 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 picogram 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 picogram was also referred to as the billionth of a gram or the millimicrogram in some countries and contexts to emphasize its extremely small size.

Example Conversions of Picograms to Other Units

Here are some examples of conversions of picograms to other units of weight:

• 1 pg = 2.2×10-15 lb
• 1 pg = 1.54×10-11 gr
• 1 pg = 1×10-15 t
• 1 pg = 1×10-12 kg
• 1 pg = 1×10-9 g
• 1 pg = 0.000001 mg
• 1 pg = 1.66×10-27 kN
• 1 pg = 3.53×10-17 oz

Grams: A Unit of Weight

Grams are a unit of weight that are used in the International System of Units (SI), also known as the metric system. Grams are derived from the French word gramme, which was taken from the Late Latin term gramma, meaning a small weight. The symbol for gram is g.

How to Convert Grams

Grams can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert grams to other units of weight in the US customary system and the SI system:

• To convert grams to ounces, divide by 28.349523125. For example, 100 g = 100 / 28.349523125 = 3.527 oz.
• To convert grams to pounds, divide by 453.59237. For example, 500 g = 500 / 453.59237 = 1.102 lb.
• To convert grams to tons (short), divide by 907184.74. For example, 1000 g = 1000 / 907184.74 = 0.0011 ton.
• To convert grams to kilograms, divide by 1000. For example, 200 g = 200 / 1000 = 0.2 kg.
• To convert grams to milligrams, multiply by 1000. For example, 50 g = 50 x 1000 = 50000 mg.
• To convert grams to micrograms, multiply by 1000000. For example, 10 g = 10 x 1000000 = 10000000 µg.
