Class 3 Mathematics: Length Conversion (Long and Short)

Vocabulary flashcards covering the key rules, methods, and examples for converting meters and mixed units to centimeters from Class 3 Mathematics.

The Golden Rule (Meters to Centimeters)

To convert meters ($\text{m}$) to centimeters ($\text{cm}$), always multiply by $100$ (or add two zeros at the end).

$$1\text{ meter (m)}$$

Equal to $100\text{ centimeters (cm)}$.

Converting Whole Meters

A process where you multiply the number of meters by $100$ (for example, $4\text{ m} = 4 \times 100 = 400\text{ cm}$).

Converting Mixed Units (Meters and Centimeters)

A two-step process where you convert the meters first (by multiplying by $100$), then add the centimeters.

Conversion of $5\text{ m } 45\text{ cm}$

A mixed conversion example solved in two steps: Step 1 converts $5\text{ m} = 5 \times 100 = 500\text{ cm}$, and Step 2 calculates $500\text{ cm} + 45\text{ cm} = 545\text{ cm}$.

Conversion of $15\text{ m}$

A simple conversion calculation yielding $1500\text{ cm}$ ($15 \times 100 = 1500\text{ cm}$).

Conversion of $1\text{ m } 7\text{ cm}$

A mixed conversion calculation yielding $107\text{ cm}$ ($100\text{ cm} + 7\text{ cm}$).

Conversion of $8\text{ m } 50\text{ cm}$

A mixed conversion calculation yielding $850\text{ cm}$ ($800\text{ cm} + 50\text{ cm}$).
