The number of grams in a tablespoon varies depending on the ingredient due to differences in density. Here are some typical conversions for common ingredients:

• Water: about 14.8 grams per tablespoon
• Milk: about 15.2 grams per tablespoon
• Cooking oil: about 13 grams per tablespoon
• All-purpose flour: about 7.8 grams per tablespoon
• Granulated sugar: about 10.4 to 12.5 grams per tablespoon
• Butter: about 14.2 grams per tablespoon
• Salt: about 17 grams per tablespoon

A general approximation often used is that 1 tablespoon is roughly equal to 14 to 15 grams for water-like liquids

. Because a tablespoon measures volume and grams measure weight, exact conversion depends on the ingredient's density. For accuracy in cooking and baking, it's best to use ingredient-specific conversion charts or calculators. For example, a tablespoon of flour weighs significantly less than a tablespoon of sugar or salt
