Kitchen measurements all connect through a few key conversions. Memorize these and most recipe math falls into place.
Volume conversions (US)
| Measure | Equals |
|---|---|
| 1 tablespoon | 3 teaspoons |
| 1 cup | 16 Tbsp = 48 tsp |
| 1 cup | 8 fluid ounces |
| 1 pint | 2 cups |
| 1 quart | 2 pints = 4 cups |
| 1 gallon | 4 quarts |
Weight vs volume
A fluid ounce (volume) is not the same as an ounce (weight) — they only match for water. For baking, weighing in grams is far more accurate than cups, because a cup of flour can vary 20%+ depending on how it’s scooped. When a recipe gives grams, use them. And watch the country: US, UK, and Australian spoons and cups differ slightly (an Australian tablespoon is 20 ml vs the US 15 ml).
Frequently asked questions
How many teaspoons in a tablespoon? 3.
Is a fluid ounce the same as an ounce? Only for water; otherwise volume and weight differ.
Why weigh ingredients? It’s far more consistent than measuring by volume.
Tape a quick-reference chart inside a cabinet door for the conversions you reach for most. And remember that dry and liquid measuring cups aren’t interchangeable: liquid cups have a spout and are filled to a line, while dry cups are meant to be leveled off flush.
