100gram

100 grams, written as 100 g, is a unit of mass in the metric system. It is equal to one-tenth of a kilogram, or 0.1 kg.

Origin and definition: The gram originated with the development of the metric system in the late 18th century. It was originally defined as the mass of one cubic centimeter of water at the temperature of its maximum density (about 4°C). In modern use, the gram is a derived unit equal to 1/1000 of a kilogram. The kilogram itself is defined in terms of fixed fundamental constants, making the gram a direct fraction of that definition.

Conversions and relations: 100 g equals 100,000 milligrams. In ounces and pounds, 100 g is about 3.53 ounces or roughly 0.22 pounds. For water, 100 g is approximately 100 milliliters, since 1 g of water is close to 1 mL under standard conditions.

Usage and context: The gram is widely used for cooking, nutrition labeling, and packaging, where quantities are often described in tens or hundreds of grams. In scientific and laboratory contexts, grams and their subdivisions (milligrams, micrograms) are common for measuring small masses. Because it is a manageable unit for everyday quantities, 100 g serves as a convenient reference amount in both consumer and educational settings.
