Step-by-step solution for: Dosage Calculations Practice Worksheet - Conversion Practice ...
To solve these conversion problems, we need to use standard conversion factors. Since the instructions say to round to the nearest tenth, we’ll apply that rule where needed.
Here’s how we’ll approach each:
- For metric conversions (like g to mg, km to m), we multiply or divide by powers of 10.
- For imperial/metric (like lb to kg, in to cm), we use known conversion factors.
- For volume (mL to cup, tsp to mL), we use standard kitchen/medical conversions.
Let’s go one by one and calculate carefully.
---
1. 1 g = ? mg
→ 1 gram = 1000 milligrams → 1000.0 mg
2. 1000 g = ? kg
→ 1000 grams = 1 kilogram → 1.0 kg
3. 1 kg = ? lb
→ 1 kg ≈ 2.20462 lb → rounded to nearest tenth → 2.2 lb
4. 1 tsp = ? mL
→ 1 teaspoon = 5 mL → 5.0 mL
5. 1000 mcg = ? mg
→ 1000 micrograms = 1 milligram → 1.0 mg
6. 1 km = ? m
→ 1 kilometer = 1000 meters → 1000.0 m
7. 10 mm = ? cm
→ 10 mm = 1 cm → 1.0 cm
8. 240 mL = ? cup
→ 1 cup ≈ 240 mL → 1.0 cup
9. 1 in = ? cm
→ 1 inch = 2.54 cm → rounded to nearest tenth → 2.5 cm
10. 100 cm = ? m
→ 100 cm = 1 m → 1.0 m
11. 1 lb = ? g
→ 1 pound ≈ 453.592 g → rounded to nearest tenth → 453.6 g
12. 1 cm = ? mm
→ 1 cm = 10 mm → 10.0 mm
13. 1 Tbsp. = ? mL
→ 1 tablespoon = 15 mL → 15.0 mL
14. 1000 mg = ? g
→ 1000 mg = 1 g → 1.0 g
15. 1 ft. = ? cm
→ 1 foot = 30.48 cm → rounded to nearest tenth → 30.5 cm
16. 30 mL = ? fl oz
→ 1 fl oz ≈ 29.5735 mL → so 30 mL ÷ 29.5735 ≈ 1.014 → rounded to nearest tenth → 1.0 fl oz
17. 12 mm = ? cm
→ 12 mm = 1.2 cm → 1.2 cm
18. 432 mcg = ? mg
→ 432 mcg ÷ 1000 = 0.432 mg → rounded to nearest tenth → 0.4 mg
19. 9926 mL = ? L
→ 9926 mL ÷ 1000 = 9.926 L → rounded to nearest tenth → 9.9 L
20. 627 cm = ? m
→ 627 cm ÷ 100 = 6.27 m → rounded to nearest tenth → 6.3 m
21. 8264 mg = ? g
→ 8264 mg ÷ 1000 = 8.264 g → rounded to nearest tenth → 8.3 g
22. 0.015 L = ? mL
→ 0.015 L × 1000 = 15 mL → 15.0 mL
23. 0.73 kg = ? g
→ 0.73 kg × 1000 = 730 g → 730.0 g
24. 45,600 mcg = ? g
→ 45,600 mcg ÷ 1,000,000 = 0.0456 g → rounded to nearest tenth → 0.0 g
*(Note: 0.0456 rounds to 0.0 when rounded to the nearest tenth — because tenths place is 0, and hundredths is 4, which is less than 5)*
25. 1.3 kg = ? g
→ 1.3 kg × 1000 = 1300 g → 1300.0 g
26. 4.5 km = ? m
→ 4.5 km × 1000 = 4500 m → 4500.0 m
27. 7.9 g = ? mg
→ 7.9 g × 1000 = 7900 mg → 7900.0 mg
28. 3.2 m = ? mm
→ 3.2 m × 1000 = 3200 mm → 3200.0 mm
29. 0.00522 g = ? mcg
→ 0.00522 g × 1,000,000 = 5220 mcg → 5220.0 mcg
30. 9850 mg = ? kg
→ 9850 mg ÷ 1,000,000 = 0.00985 kg → rounded to nearest tenth → 0.0 kg
31. 67 mL = ? L
→ 67 mL ÷ 1000 = 0.067 L → rounded to nearest tenth → 0.1 L
32. 6 lb = ? kg
→ 6 lb ÷ 2.20462 ≈ 2.72155 kg → rounded to nearest tenth → 2.7 kg
33. 10 cm = ? in
→ 10 cm ÷ 2.54 ≈ 3.937 in → rounded to nearest tenth → 3.9 in
34. 6 fl oz = ? mL
→ 6 fl oz × 29.5735 ≈ 177.441 mL → rounded to nearest tenth → 177.4 mL
35. 1.5 c = ? mL
→ 1 cup = 240 mL → 1.5 × 240 = 360 mL → 360.0 mL
36. 25 kg = ? lb
→ 25 kg × 2.20462 ≈ 55.1155 lb → rounded to nearest tenth → 55.1 lb
37. 96 in = ? cm
→ 96 in × 2.54 = 243.84 cm → rounded to nearest tenth → 243.8 cm
38. 38 lb = ? kg
→ 38 lb ÷ 2.20462 ≈ 17.236 kg → rounded to nearest tenth → 17.2 kg
39. 560 g = ? oz
→ 560 g ÷ 28.3495 ≈ 19.753 oz → rounded to nearest tenth → 19.8 oz
40. 77 mL = ? fl oz
→ 77 mL ÷ 29.5735 ≈ 2.604 fl oz → rounded to nearest tenth → 2.6 fl oz
41. 30 mL = ? tsp
→ 1 tsp = 5 mL → 30 ÷ 5 = 6 tsp → 6.0 tsp
42. 9 fl oz = ? mL
→ 9 × 29.5735 ≈ 266.1615 mL → rounded to nearest tenth → 266.2 mL
43. 5 Tbsp. = ? mL
→ 1 Tbsp = 15 mL → 5 × 15 = 75 mL → 75.0 mL
44. 165 cm = ? in
→ 165 ÷ 2.54 ≈ 64.9606 in → rounded to nearest tenth → 65.0 in
45. 44 kg = ? lb
→ 44 × 2.20462 ≈ 97.00328 lb → rounded to nearest tenth → 97.0 lb
46. 2 tsp = ? mL
→ 2 × 5 = 10 mL → 10.0 mL
