Whats my bmi and do i sound healthy?

I'm bored and feeling kinda like a slob... sitting in front of the computer all day. OK...
Anyways I was wondering what my bmi is...?
I weigh 110 pounds a.k.a 50 kgs...
I am 57 which is about 173cm...
so what is my bmi??
And is it healthy?
...

I've just turned 13 by the way (my profile says differently because this is actually my cuzies.)

Are you male or female?
What's you D.O.B.?

I'm Female... duh the picture lol...
I've just turned 13, like a week ago.

Well, you did say it was your cousin's profile...

Anyway, the BMI calculator I used said the following:
A 13 year old (female) child who is 110.0 pounds and 5 feet and 7 inches tall, has a body mass index of 17.3, which is at the 27.8th percentile and is considered to be a healthy weight.

okay well I am 5'7 and weigh 106 and mine is acaully 4.2

I did it the other day in class.

lol

so your probably some where like 5 or 7. .. .

and my health teacher says as long as you eat okay. then its not unhealthy like so many people will tell you.

no youre healthy weight because youre in the bmi of 18.5-24.5 and youre on the lower end of the scale which is good. its best to be as skinny as possible as long as youre not underweight.

ok thanks lol I'm 174 cm
I'm use to inches lol
