🔧 Understanding Metric Conversions



The metric system is based on powers of 10. Here are the common prefixes and their values:

| Prefix | Symbol | Value |
|--------|--------|-------|
| kilo- | k | 1,000 |
| hecto- | h | 100 |
| deka- | da | 10 |
| base | | 1 |
| deci- | d | 0.1 |
| centi- | c | 0.01 |
| milli- | m | 0.001 |

For length:
- 1 km = 1,000 m
- 1 m = 100 cm
- 1 cm = 10 mm

So:
- To go from larger to smaller, multiply by 10 for each step.
- To go from smaller to larger, divide by 10 for each step.

General Strategy



1. Identify the starting unit and target unit.
2. Determine how many steps apart they are.
3. Multiply or divide accordingly.

📝 Example Problem (Typical from Your Worksheet)



Let’s say one of the problems is:

> 1. 450 mm = _____ cm

Step-by-step:
- mm → cm: divide by 10
- 450 ÷ 10 = 45 cm

Answer: 45

---

Another example:

> 5. 680 cm = _____ m

- cm → m: divide by 100
- 680 ÷ 100 = 6.8 m

Answer: 6.8

💡 Tips for Solving:



- Use the conversion ladder:
km → hm → dam → m → dm → cm → mm
Each step is ×10 or ÷10.

- Move decimal point:
- From mm → cm: move 1 place left
- From cm → m: move 2 places left
- From m → km: move 3 places left
