What Are Metric Mixed Units?

Metric mixed units are measurements that combine two metric units for the same quantity.

Example:

• 1 meter 45 centimeters (1 m 45 cm)
• 3 kilograms 200 grams (3 kg 200 g)

Why Use Mixed Units?

• Sometimes measurements don’t fit exactly into one unit.
• Mixed units help express measurements more precisely and understandably.

Common Metric Mixed Units

• Length: meters and centimeters (m and cm)
• Mass (Weight): kilograms and grams (kg and g)
• Capacity (Volume): liters and milliliters (L and mL)

Conversion Basics

• 1 meter (m) = 100 centimeters (cm)
• 1 kilogram (kg) = 1,000 grams (g)
• 1 liter (L) = 1,000 milliliters (mL)

Reading Mixed Units

Read the larger unit first, followed by the smaller unit.

• Example: “2 m 30 cm” means 2 meters and 30 centimeters.

Adding Mixed Units

Add same units separately, convert if necessary.

• Example:
• 2 kg 700 g + 1 kg 500 g =
• (2 + 1) kg and (700 + 500) g =
• 3 kg 1200 g → 4 kg 200 g (because 1000 g = 1 kg)

Subtracting Mixed Units

Subtract the smaller units first. If needed, borrow from the larger unit.

• Example:
• 5 L 300 mL – 2 L 600 mL =
• Convert 1 L to 1000 mL:
• 4 L 1300 mL – 2 L 600 mL = 2 L 700 mL

Real-Life Applications

Used in measuring:

• Height (e.g., 1 m 75 cm)
• Cooking ingredients (e.g., 1 kg 250 g of sugar)
• Water bottles (e.g., 1 L 500 mL)
