An Inch of Rain

Review and Herald Publishing Association · Tacoma Park Station, Washington, D. C. · Dec 2, 1909

“So you, too, don’t know what an inch of rain is exactly,” said the weather clerk, as he looked at his rain-measuring instrument. “Very few people do, it seems. I’ll explain it to you.”

“An acre is 6,272,640 square inches. An inch of water on an acre is therefore 6,272,640 cubic inches. That amount, at 227 cubic inches to the gallon, equals 22,000 gallons, or 220,000 pounds, or 100 tons.

“An inch of rain is, in other words, rain falling at the rate of 100 tons to the acre.”—Philadelphia Bulletin.
