I have some boric acid powder and want to make a 2% solution. How do I measure the boric acid and put the right amount into the water to make 2%? Actually, it doesn't have to be exactly 2%. Even 3 or 4 percent would probably be okay. A "mild" solution, as it's to be used on the skin to try to kill tinea.
Can this be done by measuring with teaspoons? I am looking for a simple home method, I don't have any laboratory equipment.

A teaspoon in two cups of warm water is fine.

Boric acid is moderately soluble in water at room temp. About 5 g / 100 mL. So, if you want to make ~2-3%, you could just make a 100 mL saturated solution first and add another part of water (another 100 mL). That's about 2-3%.
