To solve this worksheet, we need to convert between centimeters (cm) and millimeters (mm).
The key rule given at the top of the page is:
1 centimeter (cm) = 10 millimeters (mm)
This means:
- To change
cm to mm, you multiply by 10.
- To change
mm to cm, you divide by 10.
Let’s go through each problem one by one.

Convert centimeters to millimeters (multiply by 10):
1. 96 cm → 96 × 10 =
960 mm
2. 95 cm → 95 × 10 =
950 mm
3. 39 cm → 39 × 10 =
390 mm
4. 44 cm → 44 × 10 =
440 mm
5. 12 cm → 12 × 10 =
120 mm
6. 63 cm → 63 × 10 =
630 mm
7. 37 cm → 37 × 10 =
370 mm
8. 55 cm → 55 × 10 =
550 mm
9. 83 cm → 83 × 10 =
830 mm
10. 92 cm → 92 × 10 =
920 mm

Convert millimeters to centimeters (divide by 10):
11. 61 mm → 61 ÷ 10 =
6.1 cm
12. 26 mm → 26 ÷ 10 =
2.6 cm
13. 52 mm → 52 ÷ 10 =
5.2 cm
14. 89 mm → 89 ÷ 10 =
8.9 cm
15. 90 mm → 90 ÷ 10 =
9.0 cm (or just 9 cm)
16. 96 mm → 96 ÷ 10 =
9.6 cm
17. 75 mm → 75 ÷ 10 =
7.5 cm
18. 60 mm → 60 ÷ 10 =
6.0 cm (or just 6 cm)
19. 38 mm → 38 ÷ 10 =
3.8 cm
20. 14 mm → 14 ÷ 10 =
1.4 cm
All calculations are checked — multiplying or dividing by 10 moves the decimal point one place right or left respectively.
Final Answer:
1. 960 mm
2. 950 mm
3. 390 mm
4. 440 mm
5. 120 mm
6. 630 mm
7. 370 mm
8. 550 mm
9. 830 mm
