1 exagram (Eg) = 1E+18 gram (g). Exagram (Eg) is a unit of Weight used in Metric system. Gram (g) is a unit of Weight used in Metric system.

An Introduction to Exagrams

Exagrams are a unit of mass in the metric system that are equal to one quintillion grams. They are also known as teratons or teratonnes, and are rarely used for measuring quantities of materials or substances, except in theoretical or hypothetical scenarios. In this article, we will explore the definition, history, conversion and usage of exagrams.

Definition of Exagrams

An exagram is a unit of mass equal to 10^18 (one quintillion) grams. The symbol for exagram is Eg, and it is derived from the SI prefix “exa”, meaning “quintillion”. An exagram is also equivalent to 1000000000000000 kilograms, 2204622622001001.001 pounds.

History of Exagrams

Exagrams 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.

Exagrams are also known as teratons or teratonnes, which are derived from the word “tera”, meaning “trillion”. The teraton was originally defined as the energy released by one trillion tons of TNT exploding, but was later redefined as 1000 petagrams or 4.184 yottajoules. The teraton is not an SI unit, but it is accepted for use with SI units.

How to Convert Exagrams

Exagrams can be easily converted to other units of mass by multiplying or dividing by powers of ten. For example, to convert exagrams to grams, we multiply by 10¹⁸; to convert exagrams to kilograms, we multiply by 10¹⁵; to convert exagrams to milligrams, we multiply by 10²¹.

Where Exagrams are Used

Exagrams are rarely used for measuring quantities of materials or substances, except in theoretical or hypothetical scenarios. Here are some examples:

• In cosmology, exagrams are used for estimating the mass of dark matter or dark energy in the universe. For example, the mass of dark matter in the observable universe is about 2.5 x 1024 Eg.
• In geophysics, exagrams are used for calculating the mass of tectonic plates or continental crusts on Earth. For example, the mass of the Pacific Plate is about 6.8 x 1019 Eg.
• In chemistry, exagrams are used for expressing the mass of very large molecules or macromolecules. For example, the mass of a single strand of DNA in a human cell is about 3 x 10-12 Eg.
• In mathematics, exagrams are used for illustrating very large numbers or orders of magnitude. For example, the number googolplex is equal to 10(10100) grams or 10(1098) Eg.

Example Conversions of Exagrams to Other Units

Here are some example conversions of exagrams to other units:

• To convert 5 Eg to kg, we multiply by 1000000000000000: 5 Eg x 1000000000000000 = 5000000000000000 kg
• To convert 6 Eg to lb, we multiply by 2204622622001001.001: 6 Eg x 2204622622001001.001 = 13227735732006006.006 lb

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.
