History and Origin of the Word

The French National Convention in 1795 adopted the word gramme. At that time, it was the weight of a cubic centimeter.

This decree revised the metric system by replacing the gravet, which was introduced in 1793. French gramme was derived from the Latin term gramma. The gram was considered a fundamental unit of mass in the 19th Century, used in the centimetre–gram–second system of units.

In Latin, gramma meant one twenty-fourth of an ounce, which was equivalent to 1.14 modern grams.

The gram is currently the most widely used unit of measurement for non-liquid substances and is equivalent to 0.001 of a kilogram. Over the years, the gram has been replaced by the kilogram as the official SI base unit.

Examples of the Word in Context

“The AHA limits for children vary depending on their age and caloric needs, but range between 3-6 teaspoons (12 – 25 grams) per day.”
—University of California San Francisco

“The recommended limit for the daily dose of sugar for improved health is around 11 grams, or roughly no more than 5% of daily calorie intake. According to the World Health Organization (WHO), this number should never exceed 25 grams. Many people consume far more than the recommendation.”

“The average person in the United States consumes around 17 teaspoons, or 71.14 grams, of added sugar per day, which far exceeds recommended limits. A gram (g) of sugar contains about 4 calories, which means that many people consume almost 270 calories a day from added sugar alone.”

“I weighed a piece of printer paper (4.5 grams), a plastic grocery bag (5.5 grams), and an empty soda can (13.5 grams). A plastic bag weighs more than a piece of paper, and three plastic bags exceed the weight of a can. Bags also have the added advantage of being easy to transport: You can’t stuff an empty six-pack into a single can.”
—Stanford Magazine

“Lastly, you may wonder why I use ‘grams’ (metric) instead of ‘ounces’ when I live in the United States where metric is not used. The reason is ‘gram’ measurements are so much easier to work with. You can scale a recipe up or down with little effort. But the major reason is because the word ‘ounce’ can refer to both volume (capacity) and weight (mass). There are ‘weight’ ounces and there are ‘fluid’ ounces. For example, you can have 4 ounces of flour (weight) and 4 fluid ounces of milk (volume).”
