Understanding Metric Units
Welcome to the world of metric measurements!
The metric system is used all around the world to measure length, weight, and capacity. It's based on multiples of 10, which makes converting between units super easy once you know the tricks!
Millimeter (mm)
10 mm = 1 cm
10 mm = 1 cm
Centimeter (cm)
100 cm = 1 m
100 cm = 1 m
Meter (m)
1,000 m = 1 km
1,000 m = 1 km
Kilometer (km)
For long distances
For long distances
Milliliter (mL)
1,000 mL = 1 L
1,000 mL = 1 L
Liter (L)

Gram (g)
1,000 g = 1 kg
1,000 g = 1 kg
Kilogram (kg)
Standard weight measure

How to Convert Metric Units
1️⃣ Identify what you're converting (length, weight, or capacity)
2️⃣ Remember the conversion factors (they're all based on 10s!)
3️⃣ Multiply or divide depending on whether you're going to a smaller or larger unit
Let's Practice Together!
Example 1: Length Conversion
Sarah's pencil is 15 cm long. How many millimeters is that?
Remember: 1 cm = 10 mm
Example 2: Weight Conversion
A bag of flour weighs 2.5 kg. How many grams is that?
Remember: 1 kg = 1,000 g
Parent Tips 🌟
- Kitchen conversions: Involve your child in cooking by having them convert recipe measurements (mL to L, g to kg).
- Measurement scavenger hunt: Create a game where kids find objects of specific measurements around the house.
- Real-world practice: When shopping, compare product weights in different units (500g vs 0.5kg).
