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.

 

Outcomes

5.MD.A.1

Convert customary and metric measurement units within a single system by expressing measurements of a larger unit in terms of a smaller unit. Use these conversions to solve multi-step real-world problems involving distances, intervals of time, liquid volumes, masses of objects, and money (including problems involving simple fractions or decimals). For example, 3.6 liters and 4.1 liters can be combined as 7.7 liters or 7700 milliliters.
