The Weight of Rain

How much does rain weigh? We just had a one-inch rainfall in a single thunderstorm. So let’s do some simple calculations to determine the weight of rain.

One acre of ground is 43,560 square feet. A one-inch rain is 1/12th of a foot, so the total volume of water that fell on every acre was 3,630 cubic feet. The density of water is 62.4 pounds per cubic foot. If you multiply 3,630 cubic feet by 62.4 pounds, you will see that 226,512 pounds of water (or 113.26 tons) fell on every acre of ground. There are 640 acres in a square mile, and most thunderstorms cover many square miles. So, each square mile of land received 72,486.4 tons of water in a one-inch rainfall. God’s power and energy are beyond our understanding, but we see a small piece of it in the weight of rain that falls on us.

There are many lessons involved in looking at these numbers. First, we should not underestimate the power of water to erode human structures and natural areas like the canyons we see and enjoy. We often overlook the use of water to generate electric power, and it is a renewable resource. Also, God designed water to be the basic substance of life.

The Bible refers to water many times. Proverbs 8:24-29 speaks of water as a product of wisdom and design. Psalms 23:2 refers to the peace of water and the benefits it brings. Revelation 22:1-2 repeats that, and verse 17 refers to the “water of life.” Song of Solomon 8:7 tells us that love is the only thing water cannot quench. And we need to remember that God used water to cleanse a corrupt Earth in the flood of Noah (Genesis 6:5-8).

As we learn more about other planets and moons, we see how blessed we are to be on a planet with abundant water. This is no accident. Scientists have only recently discovered the process required to make water, and we cannot overemphasize the importance of taking care of the water God gave us. Water continues to shape our planet, and we must not restrict it from what it was designed for by wasting or polluting it. How much does rain weigh? The weight of rain is great, but its value is much greater.
