Fully cooked, sweet potato

I had to tell my girlfriends about my new baby niece.  In order to give them the details I had to convert inches and pounds to centimeters and kilos. 

But, the conversion program I use is for cooking. 
 Slightly disconcerting,
     Do I convert my niece as flour or chocolate? 

And then I found it:  Sweet Potato 
Yea that sounds just right.
