There are 3 tablespoons in 1 fluid ounce.
It's important to note that ounces can be referring to fluid ounces or weight ounces, and these are not the same. Fluid ounces are used to measure liquids, while weight ounces are used to measure the weight of solids.
In the context of tablespoons, we're typically referring to measuring liquids. So, 3 tablespoons of a liquid ingredient would be equivalent to 1 fluid ounce.
