A gram (g) is a fundamental unit of mass in the metric system. It's widely used across the globe in everyday life, science, medicine, and commerce. One gram is defined as one-thousandth of a kilogram and is roughly equal to the weight of a standard paperclip or a small raisin.
The gram was introduced in France in the late 18th century during the development of the metric system. It was originally defined as the mass of one cubic centimeter of water at 4°C. Today, it's standardized based on the kilogram and remains part of the International System of Units (SI). The metric system's simplicity and global acceptance make the gram a common unit of measurement in most countries.
How Is the Gram Used: The gram is used in many areas of daily life and professional work. You'll see it often in:
The gram strikes a balance between small-scale precision and practical everyday use, making it one of the most recognized and relied-upon units in the world.
A kilogram, abbreviated as kg, is the standard unit of mass in the metric system used in nearly every country in the world. Whether you're weighing yourself at the gym, buying fruits at the grocery store, or measuring ingredients in a recipe, chances are you're using kilograms, especially if you're outside the U.S.
The term "kilogram" comes from French, combining kilo (meaning "a thousand") with gram. One kilogram equals 1,000 grams. Originally, the kilogram was defined by a physical object a platinum-iridium cylinder stored in France. But since 2019, scientists now define it using fundamental constants of nature like the Planck constant, making it far more precise and stable for scientific use.
How the Kilogram Is Used:The kilogram is part of everyday life in countries using the metric system:
1 g = 0.001 kg
Let’s say you want to convert 3,000 g to kg.
Using the formula:
3,000 × 0.001 = 3 kg
So, 3,000 g is approximately 3 kg.
