9.03 Convert units of mass

Lesson

Are you ready?

Do you remember the relationships between different units of mass? Let's try a problem to practice. 

How many grams are there in one kilogram?

  1. $16$16

    A

    $32$32

    B

    $100$100

    C

    $1000$1000

    D

Learn

We can convert between grams (g) and kilograms (kg) using the relationship:

$1$1 kilogram $=$= $1000$1000 grams

This video looks at how to convert between grams (g) and kilograms (kg).

Apply

question 1

Rewrite $1437$1437 grams in terms of the number of whole kilograms (kg) and grams (g) left over.

  1. $1437$1437 grams = $\editable{}$ whole kg and $\editable{}$ g left over.

 

Learn

We can convert between pounds (lb) and ounces (oz) using the relationship:

$1$1 pound $=$= $16$16 ounces

Apply

question 2

Convert $80$80 ounces to pounds.

 

Remember!

When you convert from a larger unit to a smaller unit (for example, kg to g), you multiply.
When you convert from a smaller unit to a larger unit (for example, oz to lb), you divide.
