recording steps walked

Hello All,
I have a question on how to record walking in other than minutes.

We are starting a walking challenge at work. We will all wear Pedometers that record our steps taken each day. It is not recording minutes or calories just steps. These are special pedometers given out by our company already set to record steps only. How can I convert the steps to the exersice log?

Any help would be appricated.

Thank you!!
