How many teaspoons does it take for 20 pound?

You can't convert pounds (a measure of weight) to teaspoons (a measure of volume). It's like asking how many apples are in a gallon of milk - they're measuring completely different things!

To help you, I need more information. What are you trying to measure?

* If you're measuring the weight of a substance: You need to know the density of the substance. For example, 20 pounds of feathers takes up a lot more space than 20 pounds of lead.

* If you're measuring the volume of a container: You need to know the volume of the container. For example, a teaspoon is 5 milliliters, so a 20-liter container holds 4000 teaspoons.

Please clarify what you're trying to do, and I can help you figure out the conversion!
