Enter the width of the mower and the speed of the mower into the calculator to determine the acres per hour.

## Acres Per Hour Formula

The following formula is used to calculate the total amount of acres per hour a lawnmower can mow.

APH = (MW/12) * (MS * 5280) / 43560 * .90

- Where APH is the acres per hour
- MW is the mower width (inches)
- MS is the mower speed (mph)

This formula assumes a 10% overlap when cutting.

## What is acres per hour?

**Definition: **

Acres per hour is a unit of square area per unit of time, in this case, acres and hours respectively.

The term is most often used in landscaping to describe how much area a lawnmower can cut per hour.

## How to caclulate acres per hour?

**Example:**

The following example problem outlines the steps and information needed to calculate how many acres per hour a lawnmower can cut.

First, determine the width of the mower. In this example, the lawnmower is measured to have a 24-inch width.

Next, determine the speed the mower can run at. This should be taken as the maximum speed. In this case, the lawnmower has a rated max speed of 15 MPH.

Finally, calculate the acres per hour the lawnmower can cut using the formula above:

APH = (MW/12) * (MS * 5280) / 43560 * .90

APH = (24/12) * (15 * 5280) / 43560 * .90

APH = 3.2727 acres per hour
