# bmi question??

Hello! I'm new, I'm 14, my name's Erika, I was diagnosed Anorexic but prefer to call myself ED-NOS.
Blablabla, anyways, I have a few questions about BMI. Thankyou in advance! :)

First of all, there's just one BMI, there isn't a standard BMI and a metric BMI, right?
Okay.
1kg = 2.2lbs, yes.
And I think, at my height of 161cm, I'm 5'2". Is that correct?
And let's say my weight is 50kg, that would make me 110lbs. Mmm?
I do my conversions here.

Okay, onto my next problem.
I calculate my BMI here, and I know it's a very popular site. Problem is, if I calculate using the statistics above -

Standard - 5'2" & 110lbs = 20.1
Metric - 161cm & 50kg = 19.3
So, either my converting is wrong, or the calculator is wrong.

Next. In Health PE class at school, we learnt that to calculate BMI, it is

Weight in kilograms divided by your height in meters squared;
So, for me it would be
50(1.61*1.61)

50(1.61*1.61)
= 50 / 2.5921
Which gives me a BMI of 19.2.

So basically, I'm confused! Can anyone solve my dilemma?
