A teaspoon is a nonSI measure of volume, with two different units  US Teaspoon and Imperial Teaspoon. Both units can be expressed as:
1 US Fluid Ounce = 6 US Teaspoons = 29.5735 milliliters
1 US Teaspoon = 1/6 US Fluid Ounce (fl oz) = 0.166666 US Fluid Ounce (fl oz) = 4.92891 milliliters
1 Imp Fluid Ounce = 4.8 Imp Teaspoon = 28.4131 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 ounces, use these formulas:
V_{(US fl oz)}= 0.166666 * V_{(US teaspoon)}= V_{(US teaspoon)} / 6
V_{(Imp fl oz)}= 0.208333 * V_{(Imp teaspoon)}=V_{(Imp teaspoon)} / 4.8
Conversion Examples
If You have 4 teaspoons (US/Imp), that would be:
V_{(US fl oz)}= V_{(US teaspoon)} / 6 = 4 / 6 = 0.666 US fl oz = 19.715 milliliters
V_{(Imp fl oz)}= V_{(Imp teaspoon)} / 4.8 = 4 / 4.8 = 0.8333 Imp fl oz = 23.677 milliliters
