Let’s solve each conversion step by step. We’ll use standard conversion factors:
- 1 gallon (gal) ≈ 3.78541 liters (L)
- 1 meter (m) ≈ 3.28084 feet (ft)
- 1 centimeter (cm) ≈ 0.393701 inches (in) → so 1 in = 2.54 cm
- 1 kilometer (km) ≈ 0.621371 miles (mi)
- 1 gram (g) ≈ 0.035274 ounces (oz)
- 1 kilogram (kg) ≈ 2.20462 pounds (lb)
- 1 quart (qt) ≈ 946.353 milliliters (mL)
We’ll round answers to 2 or 3 decimal places unless the problem suggests otherwise.
---
1) 5 L = ? gal
5 ÷ 3.78541 ≈
1.321 gal
2) 5 gal = ? L
5 × 3.78541 ≈
18.927 L
3) 30.5 m = ? ft
30.5 × 3.28084 ≈
100.066 ft
4) 75 cm = ? in
75 ÷ 2.54 ≈
29.528 in
5) 8.5 in = ? cm
8.5 × 2.54 =
21.59 cm
6) 16.9 km = ? mi
16.9 × 0.621371 ≈
10.501 mi
7) 27 g = ? oz
27 × 0.035274 ≈
0.952 oz
8) 20 kg = ? lb
20 × 2.20462 ≈
44.092 lb
9) 3800 mL = ? qt
3800 ÷ 946.353 ≈
4.015 qt
10) 1.3 qt = ? mL
1.3 × 946.353 ≈
1230.259 mL
11) 250 ft = ? m
250 ÷ 3.28084 ≈
76.200 m
12) 180 in = ? cm
180 × 2.54 =
457.2 cm
13) 100 lb = ? kg
100 ÷ 2.20462 ≈
45.359 kg
14) 9.56 oz = ? g
9.56 ÷ 0.035274 ≈
271.022 g
*(Alternatively: 9.56 × 28.3495 ≈ 271.022 g — same result)*
15) 1.16 mi = ? km
1.16 ÷ 0.621371 ≈
1.867 km
16) 291.5 L = ? gal
291.5 ÷ 3.78541 ≈
76.999 gal → almost exactly
77.000 gal
17) 10 m = ? ft
10 × 3.28084 =
32.808 ft
18) 16.1 km = ? mi
16.1 × 0.621371 ≈
10.004 mi
19) 283.5 g = ? oz
283.5 × 0.035274 ≈
10.000 oz *(exactly 10 oz — since 1 oz = 28.35 g, and 283.5 ÷ 28.35 = 10)*
20) 950 mL = ? qt
950 ÷ 946.353 ≈
1.004 qt
