# What is an inch of rain?

**inch of rain**is an

**inch**deep no matter the surface area. could be the size of a dime, could be a square

**inch**(that would give you a cubic

**inch of rain**), could be a square mile. just means that, on the whole, in a given area, enough

**rain**fell to cover the ground in an

**inch**of water (assuming zero drainage).

Considering this, is an inch of rain a lot?

Moderate **rainfall** measures 0.10 to 0.30 **inches of rain** per hour. Heavy **rainfall** is more than 0.30 **inches of rain** per hour. An **inch of rain** is exactly that, water that is one **inch** deep. One **inch of rainfall** equals 4.7 gallons of water per square yard or 22,650 gallons of water per acre!

**rain**= Depth x radius x radius x 3.14. Find the area at the top of the bucket (this is the area over which the

**rain**is collected). Divide the

**rainfall**volume by this area to get the

**rainfall**.

In respect to this, how much water is in an inch of rain?

**Water** Equivalents (approximate) One **inch of rain** falling on 1 acre of ground is equal to about 27,154 gallons and weighs about 113 tons. An **inch** of snow falling evenly on 1 acre of ground is equivalent to about 2,715 gallons of **water**.

Here are some very broad “rules of thumb.” The effective root zone for most plants extends down to about 3 feet. An **inch of rain** will wet the **soil** to a depth of **1 foot**, if there is no runoff and the **soil** is a sandy loam.
