Formula Explanation

Kitchen conversions use standard measurement equivalents. Volume-to-volume and weight-to-weight conversions are straightforward. Volume-to-weight requires knowing the ingredient density.

1 cup = 16 tbsp = 48 tsp = 8 fl oz = 236.588 mL 1 lb = 16 oz = 453.592 g 1 kg = 2.205 lbs

Tips & Best Practices

For baking, weight measurements (grams) are more accurate than volume (cups).
Remember: you cannot directly convert volume to weight without knowing the ingredient.
US cups and UK/Imperial cups are different sizes — this tool uses US cups.
When a recipe says ounces, determine if it means fluid ounces (volume) or weight ounces.

Common Mistakes to Avoid

❌ Confusing fluid ounces (volume) with ounces (weight).

✅ Fluid ounces measure volume; ounces measure weight. 8 fl oz of water weighs about 8.3 oz.

❌ Using Australian tablespoons (20 mL) with US recipes (14.8 mL).

✅ Check which country the recipe is from — this converter uses US measurements.

❌ Trying to convert cups of flour to grams without density information.

✅ Volume to weight depends on the ingredient: 1 cup flour ≈ 120g, 1 cup sugar ≈ 200g, 1 cup butter ≈ 227g.

Frequently Asked Questions

How many tablespoons in a cup?

There are 16 tablespoons in 1 US cup. There are also 48 teaspoons in 1 cup, or 8 fluid ounces.

How do I convert cups to grams?

It depends on the ingredient because different ingredients have different densities. For example, 1 cup of all-purpose flour is about 120 grams, while 1 cup of granulated sugar is about 200 grams.

What is the difference between US and UK cups?

A US cup is 236.588 mL while a UK (Imperial) cup is 284.131 mL. This can cause a 20% error in recipes if you use the wrong cup measurement. This converter uses US cups.
