If you do not have any measuring spoons but you have children then try this neat measuring tip. You will see from the picture that a child’s medicine spoon is 5ml at the large end and 2.5ml at the small end.
Therefore for a rough conversion use the following:-
1 Teaspoon = 5ml = 1 large medicine spoonful.
1 Tablespoon = 15ml = 3 large + 1 level medicine spoonfuls.
These medicine spoons fit great into baking powder and bicarbonate pots too.
