Converting between different units of measurement

Metric Conversions

Metric conversions are essential when working with different units of length, volume, and weight.

Length Conversions

• 10 mm = 1 cm
• 100 cm = 1 m
• 1 000 mm = 1 m
• 1 000 m = 1 km

Conversion Tips

• To convert to a smaller unit, multiply.
• To convert to a larger unit, divide.

Example:

• 2.5 m to cm → Multiply by 100 → 250 cm
• 320 mm to m → Divide by 1 000 → 0.32 m

Volume Conversions

• 1 000 mL = 1 L
• 1 000 L = 1 kL

Example Conversions

• 3.2 L to mL → Multiply by 1 000 → 3 200 mL
• 5 500 mL to kL → Divide by 1 000 000 → 0.0055 kL

Weight Conversions

• 1 000 mg = 1 g
• 1 000 g = 1 kg
• 1 000 kg = 1 tonne

Example Conversions

• 4.6 kg to g → Multiply by 1 000 → 4 600 g
• 3 500 mg to g → Divide by 1 000 → 3.5 g

Cooking Conversions & Temperature

Cooking measurements often use different units like cups, tablespoons, and teaspoons.

Common Cooking Conversions

• 1 cup = 250 mL
• 1 tablespoon = 15 mL
• 1 teaspoon = 5 mL

Example Conversions

• 4 cups to mL → Multiply by 250 → 1 000 mL (1 L)
• 6 teaspoons to mL → Multiply by 5 → 30 mL

Tip: Always check if you're converting to a larger or smaller unit to decide whether to multiply or divide.
