What if my POH use 'cm' and not 'mm' ?
Convert each 'cm' value to 'mm' by multiplying the 'cm' value by 10. For example, 10 cm is equal to 100 mm.




What if my POH use 'Moment/1000' ?
In the envelop settings page, you can select 'Moment/1000' in order to build the x-axis of the envelop with 'Moment/1000' values. We always advice not to use 'Moment/1000' but to use 'Inches' or 'mm'. In order to convert 'Moment/1000' value to inches or millimeters, first multiply the 'Moment/1000' value by 1000 , then divide it by the weight value, for example:

Values:
a. weight = 1500 (lbs)
b. Moment/1000 = 120 (lbs-inches)
Calculation:
1. 120 (lbs-inches) * 1000 = 120,000 (lbs-inches)
2. 120,000 (lbs-inches) / 1500 (lbs) = 80 (inches)

The same rule can be applied for Moment/1000 (kg-mm) in order to find 'mm'
