How many tea spoons is 40g of butter?

There's no direct conversion between grams of butter and teaspoons because:

* Butter density varies: The density of butter can change depending on its salt content, temperature, and how it's packed.

* Teaspoon volume varies: Teaspoons themselves can have different volumes depending on their design.

Here's a general guideline:

* 1 teaspoon of butter is roughly equivalent to 5 grams.

Therefore, 40 grams of butter is approximately equal to 8 teaspoons.

However, this is just an estimate. For more accurate measurements, it's best to use a kitchen scale.
