Is it healthy to have a six pack?

Question:

Because you have to have 10% body fat and that is considered underweight (see below)

Underweight = <18.5
Normal weight = 18.5-24.9
Overweight = 25-29.9
Obesity = BMI of 30 or greater

Answers:
The BMI scale is a piece of junk. It doesnt consider many things. You can have a bodybuilder that is 220 pounds all muscle, very low bodyfat, and the scale would indicate he/she is obese. The scale its using IS NOT A BODYFAT scale, so your calculations are wrong.

Its not unhealthy to be at 10% bodyfat, but any lower then 6% is unhealthy.
