WASHINGTON — The D.C. Metro area got clobbered as nearly five inches of rain fell across the region early Saturday morning. The range of rainfall totals is wide. While some areas got close to five inches of rain, some towns received an inch of rain or less. Numerous neighborhoods flooded as heavy rain poured across the region.
But if we took the rain amount over a given area and broke it down by the gallon, it adds up to millions of gallons of water that fell over the region. You can find these numbers by taking in to account the size of the area and the amount of rain.
For example at Ronald Reagan Washington National Airport, the National Weather Service reported four inches of rain. It is situated on a total of 860 acres: 733 acres on land and 127 acres underwater. For this calculation, we had to round up to 1,000 acres.
When we placed our numbers in the rainfall calculator, we got 108,616,000 gallons of water. According to the U.S. Geological Survey, that’s enough to fill 2,715,400 standard (40-gallon) bathtubs!
To find out how many gallons of water fell at your house you can use the simple Rainfall Calculator with the U.S. Geological Survey.
