Conversion Formulas

A teaspoon and tablespoon are non-SI measures of volume, with four different values - US and Imperial Teaspoon and Tablespoon. All four units can be expressed as:

• 1 US Tablespoon =  0.5 US Fluid Ounce = 14.78675 milliliters
• 1 Imp Tablespoon = 0.625 Imp Fluid Ounces = 17.7582 milliliters
• 1 US Teaspoon = 1/6 US Fluid Ounces = 4.92892 milliliters
• 1 Imp Teaspoon = 0.208333 Imp Fluid Ounces = 5.91939 milliliters

Thus, in order to convert volume given in teaspoons into volume given in tablespoons and vice versa, use these formulas:

V_{(US teaspoon)}= 3 * V_{(US tablespoon)}

V_{(Imp teaspoon)}= 3 * V_{(Imp tablespoon)}

Thus, we can write:

V_(teaspoon) = 3 * V_(tablespoon)

V_(tablespoon) = V_{(teaspoon) / 3}

For short, one tablespoon, regardless if it is US or Imperial, contains 3 teaspoons. Or one teaspoon contains 1/3 of a tablespoon.

Conversion Examples

If You have 18 tablespoons (US/Imp), how many teaspoons is that:

V_{(tablespoons)}= V_(teaspoon) / 3 = 18 / 3 = 6 tablespoons
