What is a tablespoon?

I know it sounds like a stupid question, but what is a tablespoon and teaspoon? Can u post pic comparing them? The reason I am asking is, I thought I was using a tablespoon but my friend points to something else (which is almost big as a ladle) as tablespoon. I am confused.

Have you tried just googling? Here's a good one that pops up: http://images.zesco.com/pimages/002/002-000-flatware1.jpg

A tablespoon in most countries is 15 ml, which is three teaspoons. It might run a bit larger in the UK and is usually around 20 ml in Australia.

I have 150ml of olive oil, taking 4 spoons every day. It should have been over in 3 days, but it's been ten days or more - still not empty. But I am sure I am using a tablespoon, not a teaspoon because teaspoon is so small ... used for sugar. that's why i am confused.

That works out to 12.5 ml per spoon, which is way bigger than a teaspoon (though smaller than a tablespoon, *shrug*). It's actually closer to a dessertspoon (don't ask).

Either it's actually much more than 150ml total or you're not using a tablespoon. If you have more precise measures you should use those. Medicine cups or spoons, for instance. You could also do it by weight. Olive oil has a density of ~0.9 g/ml, so that's about 11g per dose.
