Answer
Here are the conversions:
1. 0.65 kg = 650 g
2. 1548 g = 1.548 kg
3. 11 am = 11:00
4. 13:15 = 1:15 PM
5. 10 pm = 22:00
6. 18.5 cm = 185 mm
7. 50.54 km = 50,540 m
8. 2 m = 2000 mm
9. 12.5 g = 12,500 mg
10. 3.2 t = 3200 kg
11. 0.008 t = 8000 g
12. 200 mg = 0.2 g
13. 65,000 kg = 65 t
14. 200 mm = 20 cm
15. 14.5 g = 0.0145 kg
16. 4425.63 m = 4.42563 km
17. 37°C = 310.15 K
18. -1°C = 272.15 K
19. 273 K = -0.15°C
20. 301 K = 27.85°C
Solution
Below are the step‐by‐step conversions:
1. 0.65 kg to g
Since 1 kg = 1000 g, 0.65 kg = 0.65 × 1000 = 650 g.
2. 1548 g to kg
Since 1000 g = 1 kg, 1548 g = 1548 ÷ 1000 = 1.548 kg.
3. 11 am to digital time
“11 am” in digital format is typically written as 11:00 (or 11:00 AM).
4. 13:15 to analogue time
13:15 in the 24‑hour clock equals 1:15 PM. On an analogue clock, the hour hand points a little past 1 with the minute hand on 3.
5. 10 pm to digital time
In 24‑hour format, 10:00 PM is 22:00.
6. 18.5 cm to mm
Since 1 cm = 10 mm, 18.5 cm = 18.5 × 10 = 185 mm.
7. 50.54 km to m
Since 1 km = 1000 m, 50.54 km = 50.54 × 1000 = 50,540 m.
8. 2 m to mm
Since 1 m = 1000 mm, 2 m = 2 × 1000 = 2000 mm.
9. 12.5 g to mg
Since 1 g = 1000 mg, 12.5 g = 12.5 × 1000 = 12,500 mg.
10. 3.2 t to kg
Since 1 t (tonne) = 1000 kg, 3.2 t = 3.2 × 1000 = 3200 kg.
11. 0.008 t to g
Since 1 t = 1,000,000 g, 0.008 t = 0.008 × 1,000,000 = 8000 g.
12. 200 mg to g
Since 1 g = 1000 mg, 200 mg = 200 ÷ 1000 = 0.2 g.
13. 65,000 kg to t
Since 1 t = 1000 kg, 65,000 kg = 65,000 ÷ 1000 = 65 t.
14. 200 mm to cm
Since 1 cm = 10 mm, 200 mm = 200 ÷ 10 = 20 cm.
15. 14.5 g to kg
Since 1 kg = 1000 g, 14.5 g = 14.5 ÷ 1000 = 0.0145 kg.
16. 4425.63 m to km
Since 1 km = 1000 m, 4425.63 m = 4425.63 ÷ 1000 = 4.42563 km.
17. 37°C to K
The conversion is K = °C + 273.15, so 37°C = 37 + 273.15 = 310.15 K.
18. -1°C to K
-1°C = -1 + 273.15 = 272.15 K.
19. 273 K to °C
The conversion is °C = K - 273.15, so 273 K = 273 - 273.15 ≈ -0.15°C.
20. 301 K to °C
301 K = 301 - 273.15 = 27.85°C.
Each answer follows the standard conversion factors.

To convert \( 0.65 \mathrm{~kg} \) to grams, you simply multiply by 1000, resulting in \( 650 \mathrm{~g} \). For 1548 grams to kilograms, you divide by 1000, getting \( 1.548 \mathrm{~kg} \). Time conversions can be tricky; for 11 AM in digital format, it stays the same, but for analogue, it's simply the hour hand pointing at 11 and the minute hand at 12. As for 10 PM in digital, that's 22:00 hours! For your additional metric conversions, \( 18.5 \mathrm{~cm} \) equals \( 185 \mathrm{~mm} \), and \( 50.54 \mathrm{~km} \) translates to \( 50,540 \mathrm{~m} \). Happy converting!
