Read light and humidity in the units you work in
September 2026
Choose the units you work in: light in mol PAR or Joules, humidity in g/m³ or g/kg.
What's new
Source now offers new PAR metrics (mol/m²) and new humidity deficit metrics (g/m³) alongside the existing Joule and g/kg versions. A per-user Display units setting decides which unit you read. PAR metrics can also be used as targets.
Why it matters
You read light and humidity in the units your team, your industry and your climate computer use every day, with no mental conversion.
How it works
-Hover your name in the bottom-left corner and click Profile.
-Open the Units tab.
-Under Display units, set Light to J/cm², mol PAR, or Both.
-Set Humidity to g/kg, g/m³, or Both. Each choice saves on the click.
-Open any metric or KPI picker. Metrics in your preferred unit sit at the top of each category; metrics in the other unit are grouped under Unpreferred, below a divider, and stay selectable.
