Ballerina Weight

So I am just getting over a wedding from the weekend, full binge, but I adored it and had such a wonderful time.  Back to regular life now.

I have been using Natalie Portman from Black Swan as a Thinspo lately and I wondered, I am 5"9" what is my ballerina weight.  So I googled.  I found this interesting article on the Russian Ballet here it proved to be very interesting to read.  The basic calculation for the girls is your height subtract 127 is equal to your weight in kg.

Here is the overall equation

X = height in CM
Y = goal weight in kg

X-127=Y

Using inches to convert I am 69" tall, I used this converter I am 175.3 cm tall

Following the calculation I should be 48.3 kg

Using this calculator to get that to lbs

My ballerina weight should be 106.5
