Independent practice worksheet for converting SI units of length, focusing on meters and millimeters.

Let's solve the conversion problems step by step. We'll use the SI units of length and their relationships:

SI Unit Conversions (Length):

- 1 kilometer (km) = 1000 meters (m)
- 1 hectometer (hm) = 100 meters (m)
- 1 decameter (dam) = 10 meters (m)
- 1 meter (m) = 100 centimeters (cm)
- 1 meter (m) = 1000 millimeters (mm)
- 1 decimeter (dm) = 10 centimeters (cm) = 0.1 m
- 1 centimeter (cm) = 10 millimeters (mm)

Part a) Convert to meters

1. 5 km = ? m
$ 5 \times 1000 = 5000 $ m
✔ 5000 m

2. 0.75 km = ? m
$ 0.75 \times 1000 = 750 $ m
✔ 750 m

3. 5 hm = ? m
$ 5 \times 100 = 500 $ m
✔ 500 m

4. 10 hm = ? m
$ 10 \times 100 = 1000 $ m
✔ 1000 m

5. 4 dam = ? m
$ 4 \times 10 = 40 $ m
✔ 40 m

6. 19 dam = ? m
$ 19 \times 10 = 190 $ m
✔ 190 m

Part b) Convert to millimeters

We need to convert all lengths to millimeters (mm).

Remember:
- 1 m = 1000 mm
- 1 dm = 10 cm = 100 mm
- 1 cm = 10 mm

1. 4 m = ? mm
$ 4 \times 1000 = 4000 $ mm
✔ 4000 mm

2. 0.55 m = ? mm
$ 0.55 \times 1000 = 550 $ mm
✔ 550 mm

3. 5 dm = ? mm
Since 1 dm = 100 mm → $ 5 \times 100 = 500 $ mm
✔ 500 mm

4. 11 dm = ? mm
$ 11 \times 100 = 1100 $ mm
✔ 1100 mm

5. 4 cm = ? mm
$ 4 \times 10 = 40 $ mm
✔ 40 mm

6. 13 cm = ? mm
$ 13 \times 10 = 130 $ mm
✔ 130 mm

✔ Final Answers:

#### a) Convert to meters:
- 5 km = 5000 m
- 0.75 km = 750 m
- 5 hm = 500 m
- 10 hm = 1000 m
- 4 dam = 40 m
- 19 dam = 190 m

#### b) Convert to millimeters:
- 4 m = 4000 mm
- 0.55 m = 550 mm
- 5 dm = 500 mm
- 11 dm = 1100 mm
- 4 cm = 40 mm
- 13 cm = 130 mm
