Inconsistent calculations between metric/standard measurements.

[Dynamite]

Version: WTODS 2.2.1

I'm using the metric system to record my daily weight but I found out that the reported BMI was incorrect ( I calculated my BMI using another online service). On a whim, I converted all my measurements into the standard system ( lbs/ inch ) instead of the metric system and I got completely different results.

Steps to reproduce:
1)Download a fresh copy of the spreadsheet.
2)Change the Config. Options and input a certain starting weight and height (standard format).
3)Create a bunch of fictitious (or real if you want) entries using the standard (lbs) system.
4)Record the BMI, delta Cal/day.
5)Change the Config Options and input the same weight and height but using the metric system.
6)Convert your previously entered readings to the metric system.
7)Record the BMI, delta Cal/day.
8)Compare the two values.

In my case, the recorded values differ.
I'm using the latest version of the WTODS 2.2.1

2-a) I didnot set a starting trend set.
2-b) I didnot fill all of the listed dates.

How inconsistent are the calculations? Is the BMI completely off for metric, or could it be from the rounding?

Sorry for the late reply, but it’s been a pretty hectic weekend for me.

I went over the numbers again and I don’t believe that its a rounding error.

The BMI listed in the spreadsheet is bit larger than what other on-line BMI calculators suggest.

I'll look into it for the next release. It's possible that I may have used an incorrect metric BMI formula.
