Lesson 1: Mass

# Understanding mass (grams and kilograms)

Sal talks about what mass means. He also examines the masses of real objects in grams and kilograms.

• how much does a grown elephant weigh in kilo's
• African elephants are the largest of all land animals, adult males weighing between 1,800 and 6,300 kg (2 and 7 tons/ 4,000 and 14,000 lb.). Females are smaller, weighing between 2,700 and 3,600 kg (3 and 4 tons/ 6,000 and 8,000 lb.).
• so basically you can convert grams to kilograms by the thousands?
• To convert grams to kilograms, divide by 1,000. For example, 30,000 grams is 30 kilograms.
• How many grams in a kilogram 👨🏻‍💻
• 1000. The prefix "kilo" stands for one thousand.
• so kilo stands for thousand.
• yes, kilometers is 1,000 meters, kilograms is 1,000 grams
• hello, anybody,what are we talking about?
• We are Understanding mass in grams and kilograms
• what is the main difference between mass and weight
• Interesting question! Mass is a property of an object that does not depend on the acceleration due to gravity. Weight does depend on acceleration due to gravity. So if an object is moved from one planet to another planet, then the object's mass would not change but its weight could change.

Have a blessed, wonderful day!
• How are measurements to measure mass different than those to measure weight? How do you even measure mass? *please provide measurements of mass and weight. Sorry if I’m asking for too much. Thanks! 🙏
• Mass is basically how much matter is inside you. Weight is basically how heavy you are.
Weight is measured usually in the Customary Unit (the US system of measure) while Mass is measured usually in the Metric Units (the system of measure used by pretty much everywhere in the world).
Thanks for asking and have a great day!

• At , was Sal saying that grams are actually a unit of mass instead of weight?!
