Users will now have the ability to designate a specific patient chart to use the English or Metric system instead of the system default unit system.  The system default unit system can continue to be set from within Tools > Options > Vital Signs.

This feature was added to meet the Meaningful Use ONC 2014 Edition Test Script 170.314(a)(4) Vital Signs, Body Mass Index, and Growth Charts, that requires the EHR to allow for, "the units of measure display or are selected at the time each vital sign is entered."
