UDV calculator Formula:
Watson Formula:
   Woman: UDV = -2.097 + 0.1069 * h + 0.2466 * w
   Man: UDV = 2.477 - 0.09516 * age + 0.1074 * h + 0.3362 * w

Hume-Weyers Formula:
   Woman: UDV = (0.34454 × h) + (0.183809 × w) - 35.270121
   Man: UDV = (0.194786 × h) + (0.296785 × w) - 14.012934

Mellis & Cheek Formula (For Children):
   Boys TBW = -1.927 + 0.465 × w + 0.045 × h (for h < 132.7 cm)
            = -21.993 + 0.406 × w + 0.209 × h (for h > 132.7 cm)
   Girls TBW = 0.076 + 0.507 × w + 0.013 × h (for h < 110.8 cm)
              = -10.313 + 0.252 × w + 0.154 × h (for h > 110.8 cm)
