How to convert

1 petagram (petagram) = 1E+12 kilogram (kg). Petagram (petagram) is a unit of Weight used in Metric system. Kilogram (kg) is a unit of Weight used in Metric system.

An Introduction to Petagrams

Petagrams are a unit of mass in the metric system that are equal to one quadrillion grams. They are also known as gigatons or gigatonnes, and are commonly used for measuring extremely large quantities of materials or substances, especially in relation to climate change or geology. In this article, we will explore the definition, history, conversion and usage of petagrams.

Definition of Petagrams

A petagram is a unit of mass equal to 10^15 (one quadrillion) grams. The symbol for petagram is Pg, and it is derived from the SI prefix “peta”, meaning “quadrillion”. A petagram is also equivalent to 1000000000000 kilograms, 2204622622001.001 pounds or 5000000000000000 carats.

History of Petagrams

Petagrams were introduced as a multiplier in the metric system in 1795, along with other prefixes such as kilo, deca, deci and centi. The metric system was developed in France during the French Revolution, as a way to standardize and simplify measurements. The metric system was based on decimal fractions and powers of ten, unlike the previous systems that used arbitrary units and fractions.

The metric system was adopted by many countries in the 19th and 20th centuries, and became the official system of measurement for science and international trade. However, some countries such as the United States still use other systems such as the imperial or customary units.

Petagrams are also known as gigatons or gigatonnes, which are derived from the word “giga”, meaning “billion”. The gigaton was originally defined as the energy released by one billion tons of TNT exploding, but was later redefined as 1000 teragrams or 4.184 zettajoules. The gigaton is not an SI unit, but it is accepted for use with SI units.

How to Convert Petagrams

Petagrams can be easily converted to other units of mass by multiplying or dividing by powers of ten. For example, to convert petagrams to grams, we multiply by 1015; to convert petagrams to kilograms, we multiply by 1012; to convert petagrams to milligrams, we multiply by 1018.

Where Petagrams are Used

Petagrams are commonly used for measuring extremely large quantities of materials or substances, especially in relation to climate change or geology. Here are some examples:

  • In climatology, petagrams are used for measuring the mass of carbon dioxide or methane in the atmosphere or biosphere. For example, the global annual carbon dioxide emissions from fossil fuels and industry are about 36 Pg.
  • In geology, petagrams are used for measuring the mass of rocks or minerals in the Earth’s crust or mantle. For example, the mass of the Earth’s crust is about 2.6 x 1022 Pg.
  • In oceanography, petagrams are used for measuring the mass of water or salt in the oceans or seas. For example, the mass of the global ocean is about 1.4 x 1021 Pg.
  • In ecology, petagrams are used for measuring the mass of biomass or organic matter in terrestrial or aquatic ecosystems. For example, the global annual net primary production of plants is about 120 Pg.

Example Conversions of Petagrams to Other Units

Here are some example conversions of petagrams to other units:

  • To convert 2 Pg to g, we multiply by 1000000000000000: 2 Pg x 1000000000000000 = 2000000000000000 g
  • To convert 5 Pg to kg, we multiply by 1000000000000: 5 Pg x 1000000000000 = 5000000000000 kg
  • To convert 4 Pg to oz, we multiply by 35273962001001.001: 4 Pg x 35273962001001.001 = 141095848004004.004 oz
  • To convert 6 Pg to lb, we multiply by 2204622622001.001: 6 Pg x 2204622622001.001 = 13227735732006.006 lb
Petagrams also can be marked as Pg and Petagrammes (alternative British English spelling in UK).

Kilograms: A Unit of Weight

A kilogram is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to the mass of the International Prototype of the Kilogram (IPK), a cylinder of platinum-iridium alloy stored at the International Bureau of Weights and Measures in France. One kilogram can also be written as kg or 1000 g.

History of the Kilogram.

The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water at 4 °C, which was determined to be 18841 grains. In 1799, the Kilogramme des Archives, a platinum artifact, replaced it as the standard of weight. In 1889, the IPK became the new standard of the unit of weight for the metric system and remained so for 130 years, until the current definition was adopted in 2019.

The kilogram, as well as other metric units of weight, such as the gram and the tonne, were introduced in the 19th century as part of the decimal system of measurement that aimed to simplify and unify the units used in science and commerce. The kilogram was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units.

How to Convert Kilograms

To convert kilograms to other units of weight, we need to use conversion factors that relate the kilogram to the desired unit. For example, to convert kilograms to pounds, we need to know that one pound is equal to 0.45359237 kg. Therefore, one kilogram is equal to 2.2046226218 pounds.

Here are some common conversion factors for kilograms:

  • 1 kg = 1000 g
  • 1 kg = 2.2046226218 lb
  • 1 kg = 35.27396195 oz
  • 1 kg = 0.001 t
  • 1 kg = 0.1574730444 st

To convert from other units of weight to kilograms, we need to use the inverse of these conversion factors. For example, to convert pounds to kilograms, we need to divide by 2.2046226218.

Kilograms also can be marked as kilogrammes in UK.
