Mastering Metric Conversions: From Grams to Tonnes

Learning Objective

Understand the conversion between grams, kilograms, and tonnes and apply it to solve problems.

What do you already know about converting between grams, kilograms, and tonnes?

Understanding the Metric System

The metric system is based on powers of 10. Grams, kilograms, and tonnes are units of mass in this system.

Converting Grams to Kilograms

To convert grams to kilograms, divide by 1000. For example, 3000g = 3kg.

Converting Kilograms to Grams

To convert kilograms to grams, multiply by 1000. For example, 5kg = 5000g.

Converting Kilograms to Tonnes

To convert kilograms to tonnes, divide by 1000. For example, 5000kg = 5t.

Converting Tonnes to Kilograms

To convert tonnes to kilograms, multiply by 1000. For example, 3t = 3000kg.

Converting Grams to Tonnes

To convert grams to tonnes, divide by 1,000,000. For example, 500,000g = 0.5t.

Putting It All Together

Practice converting between grams, kilograms, and tonnes with a variety of exercises.
