In this lesson, you'll learn a quick way to converts acres to hectares, followed by a more detailed explanation of how to do this, and then a way you can check your work.

Conversion In Detail

Let's say you want to convert 100 acres to hectares. How do we do this? Use the following steps:

1. You need to know that 1 acre = 0.404686 hectares and/or 1 hectare = 2.471 acres depending on the conversion

2. Always write down the units of your eventual answer (hectares in this case) to the right side of the equation like so:


This helps you 'see' that you are working your way towards getting an answer in hectares.

3. With that out of the way, you need to know that when you are converting from one unit type (acres) to another (hectares), the units you are converting from (acres) must cancel out during the conversion process. This can only happen if the units you want to cancel out, acres, are on the opposite side of the fraction bar, like so:


4. This way, the units of acre(s) cancel out and you are left with a simple multiplication step of:

100 x 0.404686 hectares = 40.47 hectares


100 acres = 40.47 hectares

Check Your Work

How can we double check that this is correct? Remember, 1 hectacre = 2.471 acres as well. So, using the principles outlined in the steps above we can use this conversion to convert 100 acres into hectares like so:
