To change a metric in Mixpanel from showing an abbreviated number (e.g., 1.2K) to the actual full figure, you need to adjust the unit configuration for that metric. In the metric unit settings (found at the bottom left of every metric block), you can choose whether or not the result should be abbreviated. Disabling abbreviation will display the full, unshortened number in your reports, tooltips, and tables. This setting can be saved to your report and will persist in the board view as well.
“Abbreviation: choose whether or not the result should be abbreviated. Useful for large numbers”
