Rainfall calculator (English units)

How much water falls during a storm? Use our metric-system version. It is the middle of July in Georgia and both you and your tomatoes are wilting in your yard, both looking to the sky and hoping for rain. Or, maybe a low-pressure cell has been napping overhead, and your arm is hurting from holding that umbrella while you watch your basement fill up with water. Either way, you would like to know how much rain has fallen—how many gallons have come down from the skies onto your roof, yard, block, or town. You might even want to know how many baths you could get from your rainstorm? In the form below, choose an area(s) and a rainfall amount to see how many gallons of water fell from the sky onto that area. I think you'll be surprised about much rain really does fall during a rainstorm. Note: You can enter numbers into any or all of the boxes below: Method A : Use FEET (for areas such as your yard).
