## 📏 Metric Conversion Basics

The metric system uses prefixes that represent powers of 10. Here are the key relationships used in this worksheet:

Length:


- 1 meter (m) = 100 centimeters (cm)
- 1 centimeter (cm) = 10 millimeters (mm)
- 1 kilometer (km) = 1000 meters (m)

Mass:


- 1 kilogram (kg) = 1000 grams (g)

Volume:


- 1 liter (L) = 1000 milliliters (mL)

## 🔁 How to Convert

➤ To convert from a larger unit to a smaller unit, multiply by the conversion factor.


> Example: 5 m → cm → 5 × 100 = 500 cm

➤ To convert from a smaller unit to a larger unit, divide by the conversion factor.


> Example: 8000 mL → L → 8000 ÷ 1000 = 8 L

---

## Let’s Verify a Few Examples from the Sheet

---

1) 5 m = 500 cm


→ 5 × 100 = 500 cm ✔️

2) 8000 mL = 8 L


→ 8000 ÷ 1000 = 8 L ✔️

3) 4 L = 4000 mL


→ 4 × 1000 = 4000 mL ✔️

4) 8 cm = 80 mm


→ 8 × 10 = 80 mm ✔️

5) 9000 g = 9 kg


→ 9000 ÷ 1000 = 9 kg ✔️

6) 7 m = 700 cm


→ 7 × 100 = 700 cm ✔️

7) 70 mm = 7 cm


→ 70 ÷ 10 = 7 cm ✔️

8) 10 kg = 10000 g


→ 10 × 1000 = 10000 g ✔️

9) 10000 g = 10 kg


→ 10000 ÷ 1000 = 10 kg ✔️

## 🎯 Pattern Recognition

Notice that all conversions here involve multiplying or dividing by 10, 100, or 1000 — which just means moving the decimal point!

- Multiply by 10 → move decimal 1 place right
- Multiply by 100 → move decimal 2 places right
- Multiply by 1000 → move decimal 3 places right
- Divide by 10 → move decimal 1 place left
- etc.

## 🧠 Tip for Students

Use this “metric staircase” memory aid:

```
kilo (1000)
|
hecto (100)
|
deca (10)
|
[base unit: m, g, L]
|
deci (0.1)
|
centi (0.01)
|
milli (0.001)
```

Each step up = divide by 10
Each step down = multiply by 10

## ✍️ If You Were Given the Blank Worksheet...

You’d be asked to fill in the blanks like:

> 1) ___ m = 500 cm → Answer: 5
> 2) 8000 mL = ___ L → Answer: 8
> 3) 4 L = ___ mL → Answer: 4000

And so on.

## 📌 Summary

The image you uploaded is the answer key.
All conversions follow simple multiplication/division by 10, 100, or 1000.
Understanding these relationships helps you convert ANY metric unit confidently.
