Converting Customary Units - Free Printable

Let’s solve each part step by step.

We need to remember these basic conversions:
- 1 pint = 2 cups
- 1 quart = 2 pints → so 1 quart = 4 cups
- 1 gallon = 4 quarts → so 1 gallon = 8 pints → and 1 gallon = 16 cups

Now let’s go question by question.

---

Fill in the blanks:

1) 1 pint = 2 cups
2) 4 quarts = 1 gallon
3) 1 gallon = 8 pints
4) 1 quart = 4 cups
5) 16 cups = 1 gallon
6) 1 quart = 2 pints
7) 2 quarts = 2 × 4 = 8 cups
8) 2 gallons = 2 × 4 = 8 quarts
9) 3 pints = 3 × 2 = 6 cups
10) 3 quarts = 3 × 2 = 6 pints → 6 pints = 3 quarts
11) 2 gallons = 2 × 8 = 16 pints
12) 5 pints = 5 × 2 = 10 cups
13) 3 quarts = 3 × 4 = 12 cups
14) 8 cups = 8 ÷ 2 = 4 pints
15) 4 pints = 4 ÷ 2 = 2 quarts
16) 4 quarts = 4 × 2 = 8 pints
17) 12 cups = 12 ÷ 2 = 6 pints
18) 4 quarts = 4 × 4 = 16 cups
19) 10 pints = 10 ÷ 2 = 5 quarts
20) 8 quarts = 8 ÷ 4 = 2 gallons

Which is most? Circle the largest amount in each box.

First box:
- 1 gallon = 16 cups
- 10 pints = 20 cups
- 12 cups = 12 cups
→ Largest: 10 pints

Second box:
- 9 cups = 9 cups
- 3 quarts = 12 cups
- 5 pints = 10 cups
→ Largest: 3 quarts

Third box:
- 17 cups = 17 cups
- 1 gallon = 16 cups
- 7 pints = 14 cups
→ Largest: 17 cups

Fourth box:
- 5 quarts = 20 cups
- 1 gallon = 16 cups
- 11 pints = 22 cups
→ Largest: 11 pints

Wait — let me double-check that last one:

5 quarts = 5 × 4 = 20 cups
1 gallon = 16 cups
11 pints = 11 × 2 = 22 cups → yes, 22 > 20 → so 11 pints is largest.

But wait — actually, let’s convert everything to the same unit (cups) for accuracy.

Box 1:
1 gal = 16 c
10 pt = 20 c
12 c = 12 c → max = 20 → 10 pints

Box 2:
9 c
3 qt = 12 c
5 pt = 10 c → max = 12 → 3 quarts

Box 3:
17 c
1 gal = 16 c
7 pt = 14 c → max = 17 → 17 cups

Box 4:
5 qt = 20 c
1 gal = 16 c
11 pt = 22 c → max = 22 → 11 pints

✔ Correct.

Put these liquid measures in order from smallest to largest:

Given:
1 gallon, 17 cups, 7 pints, 3 quarts

Convert all to cups:

- 1 gallon = 16 cups
- 17 cups = 17 cups
- 7 pints = 7 × 2 = 14 cups
- 3 quarts = 3 × 4 = 12 cups

So in cups:
3 quarts = 12
7 pints = 14
1 gallon = 16
17 cups = 17

Order from smallest to largest:
3 quarts, 7 pints, 1 gallon, 17 cups
