What is a Gram (g)?

A gram (g) is a metric unit for measuring light things. It is the smaller, everyday cousin of the kilogram—in fact, it takes 1,000 grams to make 1 kilogram. It is commonly used for measuring relatively small quantities of food, ingredients, medicines, and other everyday items.

A gram weighs about as much as a standard paperclip, a US dollar bill, or a teaspoon of water.

• 1 gram = 0.001 kilogram
• 1 kilogram = 1,000 grams
• 1 gram ≈ 0.035274 ounces

We use grams in the USA for:

• Food and recipes (flour, sugar, coffee)
• Jewellery and gold weight
• Postage (weighing letters and small packages)
• Nutrition labels
• Science labs (chemicals and samples)

What is a Kilogram (KG)?

A kilogram (kg) is a standard metric unit used to measure mass or weight. A kilogram is 1000 grams. It’s the main metric unit for heavier things like body weight, luggage, and bulk food.

• 1 kilogram = 1,000 grams
• 1 kilogram = 1,000,000 milligrams
• 1 kilogram ≈ 2.20462 pounds (lb)

In the USA, kilograms are commonly used in science, healthcare, fitness, shipping, and international measurements, while pounds are more commonly used in everyday life.

Going from KG to grams? Do the opposite—multiply by 1,000.

The easiest formula:

To convert KG back to grams:
