Operations with metric units

In this lesson, we will learn:

• Adding mixed metric units
• Subtracting mixed metric units

Notes:

Metric Units of Length:

1km = 1000 m
1 m = 100 cm
1 cm = 10 mm





Metric Units of Volume

1L = 1000 mL




Metric Units of Weight 

1kg = 1000 g



-to add or subtract measurements measurements must be in the SAME units

Adding Mixed Metric Units Steps

1. Group together like units
2. Add like units (starting with smaller units)
3. Rename and Regroup units (if you need to)

Subtracting Metric Units Steps

1. Group together like units
2. Rename and regroup units (if you need to)
3. Subtract like units
