Let’s solve each conversion step by step. We’ll use standard conversion factors:

- 1 liter (L) ≈ 0.264172 gallons (gal)
- 1 gallon (gal) ≈ 3.78541 liters (L)
- 1 meter (m) ≈ 3.28084 feet (ft)
- 1 centimeter (cm) ≈ 0.393701 inches (in)
- 1 inch (in) = 2.54 centimeters (cm)
- 1 kilometer (km) ≈ 0.621371 miles (mi)
- 1 gram (g) ≈ 0.035274 ounces (oz)
- 1 kilogram (kg) ≈ 2.20462 pounds (lb)
- 1 milliliter (mL) = 0.001 L → so 1 mL ≈ 0.000264172 gal, but better to convert via quarts:
- 1 quart (qt) = 946.353 mL → so 1 mL ≈ 0.00105669 qt
- 1 foot (ft) ≈ 0.3048 meters (m)
- 1 pound (lb) ≈ 0.453592 kg
- 1 mile (mi) ≈ 1.60934 km

We’ll calculate each one carefully.

1) 5 L = ? gal
5 × 0.264172 ≈ 1.32086 gal → round to 2 decimals: 1.32 gal

2) 5 gal = ? L
5 × 3.78541 ≈ 18.92705 L → 18.93 L

3) 30.5 m = ? ft
30.5 × 3.28084 ≈ 100.06562 ft → 100.07 ft

4) 75 cm = ? in
75 × 0.393701 ≈ 29.527575 in → 29.53 in

5) 8.5 in = ? cm
8.5 × 2.54 = 21.59 cm (exact)

6) 16.9 km = ? mi
16.9 × 0.621371 ≈ 10.5011699 mi → 10.50 mi

7) 27 g = ? oz
27 × 0.035274 ≈ 0.952398 oz → 0.95 oz

8) 20 kg = ? lb
20 × 2.20462 ≈ 44.0924 lb → 44.09 lb

9) 3800 mL = ? qt
3800 ÷ 946.353 ≈ 4.0154 qt → 4.02 qt

10) 1.3 qt = ? mL
1.3 × 946.353 ≈ 1230.2589 mL → 1230.26 mL

11) 250 ft = ? m
250 × 0.3048 = 76.2 m (exact)

12) 180 in = ? cm
180 × 2.54 = 457.2 cm (exact)

13) 100 lb = ? kg
100 × 0.453592 = 45.3592 kg → 45.36 kg

14) 9.56 oz = ? g
9.56 ÷ 0.035274 ≈ ? Wait — better: since 1 g = 0.035274 oz, then 1 oz = 1 / 0.035274 ≈ 28.3495 g
So 9.56 × 28.3495 ≈ 271.02122 g → 271.02 g

15) 1.16 mi = ? km
1.16 × 1.60934 ≈ 1.8668344 km → 1.87 km

16) 291.5 L = ? gal
291.5 × 0.264172 ≈ 77.006138 gal → 77.01 gal

17) 10 m = ? ft
10 × 3.28084 = 32.8084 ft → 32.81 ft

18) 16.1 km = ? mi
16.1 × 0.621371 ≈ 10.0040731 mi → 10.00 mi

19) 283.5 g = ? oz
283.5 × 0.035274 ≈ 10.000179 oz → 10.00 oz (very close to exact!)

20) 950 mL = ? qt
950 ÷ 946.353 ≈ 1.00385 qt → 1.00 qt
