I was at my Nana's the other day and we actually tested out this measurement conversion... I'm sure we were doing something with a recipe... maybe halving it? I'm not certain, but I do know she pulled out a shot glass and a tablespoon, handed me a bowl of water and said, "let's find out!".
My Nana is the kind of woman who likes people to figure stuff out and is very hands on, so googling it wasn't good enough for her, but I did use asknumbers.com for this #googleit (because I was confident in the first google result as it matched with my own findings). Bottom line, the answer to the question is: there are 2 tablespoons to 1 ounce.
