In Photoshop, how do I change units from metric to imperial (inches)?

I'll add my 2 cents worth.  Chuck's suggestion is the usual way.  It is quick, easy, and can be done on the fly.  If you have an image that was created with a metric size, open up the image size dialog, and uncheck Resample.  Then use the size drop down and chose your unit.

After

Note that you won't normally get a nice rounded result like above, depending on the number of pixels.   In this instance 1 Inch = 25.4mm so it worked out nicely.

Hi Michelineh,

Please follow the below steps to change the units in Photoshop.

> Launch Photoshop

> Click Photoshop > Preferences > Units & Rulers (In Mac)

               Edit > Preferences > Units & Rulers (In Windows)

> Change Rulers to Inches

> Click on Ok.

> Relaunch Photoshop and check for the issue.

Hope this helps.
