Create a variable/field to convert weight?

Hi,

My weight is set in lbs in Intervals and I prefer that for my scales and weighing at home but sometimes I am asked about my weight in life and they want in in KG, is there a way to have a variable/field setup to do the calculation so I can use lbs and show a KG value for reference?

Ideally I would like to build a chart that shows this in both values?

You can do this easily on the Fitness page using two plots. If your weight in Intervals is in lbs, select Formula for the second plot and divide weight by 2.2 to convert to kg. I have it set the other way around, so I multiply kg by 2.2 to convert to lbs (screenshot). Then set your lbs plot as one y-axis scale label and your kg plot for the other.
