How to convert teaspoons to cups
cups = teaspoons ÷ 48
Example: 4 tsp ÷ 48 = 0.08333 cup.
Divide the teaspoons by 48. One teaspoon is a tiny share of a cup, so this math pays off only for large counts.
A two-step route is easier to do in your head: divide by 3 for tablespoons, then by 16 for cups. 30 teaspoons become 10 tablespoons, which is 5/8 cup.
Thirds of a cup come out even too: 32 teaspoons make exactly 2/3 cup. For counts in between, measure the largest cup that fits and finish with spoons.
For example, 40 teaspoons come to 0.8333 cup. Fill a 3/4 cup measure, then add 4 teaspoons, which you can scoop as 1 tablespoon plus 1 teaspoon.
US vs UK teaspoons and cups
Recipes written with metric measures need a different divisor. A metric cup of 250 ml takes 50 teaspoons of 5 ml, so divide by that number instead.
The two systems still land close together. 48 teaspoons of the metric kind make 240 ml, the size of the cup on US nutrition labels and only slightly more than a US cup of 236.6 ml.
| Unit | Size | Used in |
|---|---|---|
| US teaspoon | 4.929 ml | US |
| metric teaspoon | 5 ml | UK, Australia, Canada, New Zealand |
| US cup | 236.6 ml | US |
| US legal cup | 240 ml | US nutrition labels |
| metric cup | 250 ml | UK, Australia, Canada, New Zealand |
How do you scale spices up for a crowd?
Teaspoon amounts grow fast in big batches. A rub that uses 2 teaspoons of cumin per rack of ribs needs 16 teaspoons for eight racks, and that is 1/3 cup.
Measure whole cups first, then add the leftover teaspoons, so you count a few spoonfuls instead of dozens. To split a cup back into small doses, see cups to teaspoons.
Teaspoons and cups: questions
How many cups is 12 teaspoons?
12 teaspoons fill 1/4 cup, the same as 4 tablespoons. A 1/4 cup measure is quicker than twelve separate scoops. The 12 teaspoons page shows the math step by step.
How many cups is 24 teaspoons?
24 teaspoons make 1/2 cup. That is 8 tablespoons, or 4 fluid ounces of a liquid, so a liquid measuring cup with ounce lines works as well as spoons.
How many cups is 36 teaspoons?
36 teaspoons equal 12 tablespoons, and that fills a 3/4 cup measure exactly. One level scoop replaces three dozen spoonfuls and the risk of losing count.
How many teaspoons make 1/8 cup?
6 teaspoons make 1/8 cup, which is also 2 tablespoons or 1 fluid ounce. Two level tablespoons are the easiest way to measure it, and they are more precise than reading a line near the bottom of a large cup.
Is a teaspoon 1/48 of a cup?
Yes. A US cup holds 48 teaspoons, so one teaspoon is 1/48 of a cup, or about 0.021 cup as a decimal. With metric spoons and a metric cup, the share is 1/50.
