Enter any 3 values to calculate the missing variable

The **Acre Foot of Water Calculator** is a vital tool for measuring large volumes of water, especially in agriculture, pond management, and water conservation. An acre-foot is the amount of water needed to cover one acre of land to a depth of one foot, which equals **325,851 gallons**.

This makes it smooth and easy of converting land area and water depth into accurate volume measurements. Whether you need to calculate water requirements for irrigation or determine the volume in a pond, this tool offers quick and precise results for both **farmers** and **water managers**.

**Formula:**

$V = \frac{L \times W \times D}{43,560}$

Variable | Meaning |
---|---|

V |
Volume in acre-feet |

L |
Length of the area in feet |

W |
Width of the area in feet |

D |
Depth of the water in feet |

43,560 |
Conversion factor (square feet in one acre) |

**Solved Calculations :**

**Example 1:**

**Given Values**:

**L**= 100 feet**W**= 50 feet**D**= 10 feet

Calculation | Instructions |
---|---|

V = $\frac{100 \times 50 \times 10}{43,560}$ | Multiply the length, width, and depth, then divide by 43,560. |

V = $\frac{50,000}{43,560}$ | Perform the multiplication and division. |

V ≈ 1.15 acre-feet | The result gives the volume in acre-feet. |

**Answer**: V ≈ 1.15 acre-feet

**Example 2:**

**Given Values**:

**L**= 200 feet**W**= 100 feet**D**= 5 feet

Calculation | Instructions |
---|---|

V = $\frac{200 \times 100 \times 5}{43,560}$ | Multiply the length, width, and depth, then divide by 43,560. |

V = $\frac{100,000}{43,560}$ | Perform the multiplication and division. |

V ≈ 2.30 acre-feet | The result gives the volume in acre-feet. |

**Answer**: V ≈ 2.30 acre-feet

**What is Acre Foot of Water Calculator ?**

An **acre-foot of water** is a standard unit used to measure large-scale water resources, typically in agriculture and water management. It is commonly used in the United States to measure water volumes in ponds, lakes, or irrigated fields. For example, a 1-acre pond with a depth of 1 foot contains 1 acre-foot of water, equivalent to **325,851 gallons**.

The **Acre Foot of Water Calculator** allows you to enter the dimensions of your water source (such as length, width, and depth) to determine how many acre-feet of water it contains. This tool simplifies the task of converting land and water measurements into usable data.

Farmers often rely on this calculation to determine how much water is required for **irrigation** based on the size of their fields. Likewise, pond managers can use it to estimate the water capacity of their ponds. This calculator is particularly useful in areas where water conservation is critical, such as Texas or California.

**Final Words:**

Whether you’re dealing with large-scale irrigation or managing a pond, the **Acre Foot of Water Calculator** provides an accurate measure of water volume, ensuring efficient resource management and proper planning for agricultural or environmental needs.
