# Proportional Body Calculator: McCallum's Formula

Discover the concept of body proportionality with McCallum's Formula.

Developed by expert methodist John McCallum, this formula is based on the measurement of wrist girth. While it provides valuable insights, it's important to note that this formula may not be applicable to everyone, as it assumes a strong correlation between wrist size and the size of other human bones.

The formula follows this logical framework:

```
The waist girth is approximately 6.5 times the chest girth.
The waist girth is approximately 70% of the chest girth.
The hip girth is approximately 53% of the chest girth.
The neck girth is approximately 37% of the chest girth.
The biceps girth is approximately 36% of the chest girth.
The lower leg girth is approximately 34% of the chest girth.
The forearm girth is approximately 29% of the chest girth.
