A teaspoon is about the size of the tip of your finger (joint to tip). A tablespoon is about the size of half a ping-pong ball or the size of an ice cube. 1/4 cup is about the size of a large egg. 1/2 cup is about the size of a tennis ball.
A teaspoon is a unit of volume measure equal to 1/3 tablespoon. It is exactly equal to 5 mL. "Teaspoon" may be abbreviated as t (note: lowercase letter t) or tsp. A small spoon, as might be used for eating yogurt from a small container or adding sugar to tea, is about 1 teaspoon in size.

Silva is one of the strongest Nen users in the world from Gin's generation. Chrollo, Hisoka and Illumi are around the same bracket of power and the same Generation, Zeno is as well (power wise). Silva is obviously stronger than Illumi and Zeno so it wouldn't make sense for Silva to be in the same bracket as them.
