If you want to measure the length of a spoon, you'd use centimeters or millimeters. If you want to measure its capacity (how much it could hold), you'd use milliliters.

Vanilla extract is liquid, so use measuring spoons to measure it, or for large quantities use a measuring cup for liquids. Vanilla powder can be measured with measuring spoons or a measuring cup for solids. Whole bean vanilla doesn't usually need a measuring device, since the recipe will say something like "seeds of 1 whole vanilla bean."
Centimetres, millimetres or inches would be most appropriate for measuring the length of a ruler.
If you do not have a means to meaure quantities accurately, you can still estimate. But bear in mind, measuring cups are not expensive. They're pretty easy to get.
