Various Conversion Factors

Home > Free Information > Conversion Factors

The question often comes up about the proper mixing of pesticides or fertilizers, especially when the label states "40 ounces per 500 gallons," and you only want to make up a gallon of spray! The charts of conversion factors below will be a great help in figuring out those oddballs. (The "household" measurements - teaspoons, tablespoons, cups, gallons, etc. - are US measurements, not Imperial) It's a bit too big to conveniently read on-line, but the Acrobat *.PDF file prints nicely on one landscape page.

If you see an error, or see the need for another factor, please email me.

(By the way, "40 ounces per 500 gallons" is roughly 1/2 teaspoon per gallon, or 0.5-0.6ml/L)
