BMI calculations

[Topaz63]

Interestingly, I get a higher BMI from Ticker Factory than when I use the NHS calculation. Has anyone an explanation?
For me this is sort of important because of what DD says about fat cells splitting into two daughter cells, which his research suggests starts to happen at around BMI 28 or so. On NHs calc I was just over 28 when I started, but on this site I was at 30.
The NHS calc is your weight in kilos divided by your height in metres squared.

I suspect it's down to the difference in calculating imperial v metric.

Are you sure the metric you are inputting the nhs site is exactly equivalent to the imperial statistics you are using on this site?

This nhs calculator has imperial input -
BMI healthy weight calculator - Health tools - NHS Choices
- so you could double check.

I used the formula on that site as the calculator won't come up on iPhone or iPad. Will try later on proper computer. Could be. But I noticed this when I first started on minimins, having originally used the NHS. Site calculator on my computer. Just felt glum and didnt think to ask you all.
