The gram (originally gramme;^[one] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one 1 thousandth of a kilogram.

Originally defined every bit of 1795 as "the absolute weight of a book of pure water equal to the cube of the hundredth function of a metre [1 cm³], and at the temperature of melting ice",^[2] the defining temperature (~0 °C) was later inverse to 4 °C, the temperature of maximum density of water.

However, by the late 19th century, there was an effort to make the base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units divers a gram as i one-thousandth of a kilogram (i.e., one gram is 1×10⁻³ kg). The kilogram, as of 2019, is defined by the International Agency of Weights and Measures from the fixed numerical value of the Planck constant ( $h$ ), which is 6.626070 15 ×10⁻³⁴ kg⋅grand²⋅s⁻¹.^[3] ^[4]

Official SI symbol [edit]

The only unit symbol for gram that is recognised by the International System of Units (SI) is "g" following the numeric value with a space, equally in "640 g" to stand for "640 grams" in the English language. The SI does not back up the use of abbreviations such as "gr" (which is the symbol for grains),^[5] ^: C-19 "gm" ("g⋅m" is the SI symbol for gram-metre) or "Gm" (the SI symbol for gigametre).

History [edit]

The word gramme was adopted by the French National Convention in its 1795 decree revising the metric system every bit replacing the gravet introduced in 1793. Its definition remained that of the weight (poids) of a cubic centimetre of water.^{[half dozen]} ^[7]

French gramme was taken from the Late Latin term gramma . This word—ultimately from Greek γράμμα (grámma), "letter"—had adopted a specialised pregnant in Belatedly Antiquity of "one 20-quaternary part of an ounce" (two oboli),^[8] corresponding to about 1.14 modern grams. This use of the term is found in the carmen de ponderibus et mensuris ("verse form nigh weights and measures") composed around 400 Ad.^[a] There is also prove that the Greek γράμμα was used in the same sense at effectually the same fourth dimension, in the 4th century, and survived in this sense into Medieval Greek,^[10] while the Latin term did not remain current in Medieval Latin and was recovered in Renaissance scholarship.^[b]

The gram was the fundamental unit of mass in the 19th-century centimetre–gram–second arrangement of units (CGS). The CGS system co-existed with the meter-kilogramme-2d arrangement of units (MKS), first proposed in 1901, during much of the 20th century, but the gram has been displaced by the kilogram as the fundamental unit for mass when the MKS system was chosen for the SI base of operations units in 1960.

Uses [edit]

The gram is today the most widely used unit for not-liquid ingredients in cooking and grocery shopping worldwide.^[11] ^[12] Liquid ingredients may be measured by volume rather than mass.

Many standards and legal requirements for nutrition labels on food products crave relative contents to exist stated per 100 g of the product, such that the resulting figure can also exist read as a percentage.

Comparisons [edit]

ane gram is roughly equal to 1 pocket-size paper prune or pen cap.
The Japanese 1 yen coin has a mass of ane gram,^[14] lighter than the British penny (3.56 thousand), the U.s.a. penny (2.5 thousand), the Euro cent (ii.30 chiliad), and the Australian 5 cent coin (2.80 g).

Notes [edit]

^ The appointment and authorship of this Late Latin didactic poem are both uncertain; it was attributed to Priscian but is at present attributed to Rem(m)ius Favinus/Flav(in)us.^[9] The poem'southward title is reflected in the French phrase poids et mesures ("weights and mesures") in the championship of the 1795 National Convention decree, Décret relatif aux poids et aux mesures that introduced the gram, and indirectly in the proper name of the General Briefing on Weights and Measures responsible for the modern definition of the metric units.
^ In the Renaissance, the carmen de ponderibus et mensuris was received every bit a work of the 1st-century grammarian Remmius Palaemon edited in 1528 past Johann Setzer of Hagenau, together with works by Celsius, Priscian and Johannes Caesarius; Aurelij Cornelij Celsi, De re medica, libri octo eruditissimi. Q. Sereni Samonici Praecepta medica, uersibus hexametris. Q. Rhemnij Fannij Palaemonis, De ponderibus [et] mensuris, liber rarus [et] utilissimus
