The Ideal Body Weight (IBW) and Adjusted Body Weight (ABW) calculator uses the Devine formula to provide two key metrics based on an individual's input details, including gender, height, and actual weight, offering insight into weight management.

The process begins by understanding the inputs:

- Gender is selected either as Male or Female, which influences the IBW calculation.
- Height can be entered in centimeters (cm) or inches (in). When entered in centimeters, it is first converted to inches by dividing by 2.54 to align with the formula's requirements.
- Actual weight is provided in kilograms (kg) or pounds (lbs). It is converted to kilograms if entered in pounds by dividing by 2.20462, ensuring consistency in calculations.

The computations then proceed with:

- Calculating Ideal Body Weight (IBW):
  - For males, IBW is computed using the formula: 50 + (2.3 * (height in inches - 60)).
  - For females, the formula is: 45.5 + (2.3 * (height in inches - 60)).
  - This IBW calculation reflects an incremental increase based on height above 60 inches and varies according to gender.

- Determining Adjusted Body Weight (ABW):
  - ABW is calculated as IBW + (0.4 * (actual weight in kg - IBW)).
  - The ABW is an adaptation that considers the variation between actual and ideal weights, adjusting IBW by 40% of the excess of actual weight.

- Presenting Actual Weight:
  - After calculations, the actual weight is displayed in the original unit chosen by the user, either in kilograms or pounds, maintaining consistency with the initial input.

Finally, the results offer insights into body weight management:

- The Ideal Body Weight (IBW) suggests a target weight associated with the individual’s height and gender.
- The Adjusted Body Weight (ABW) provides a tailored weight value, especially useful when the actual weight significantly deviates from the IBW.
- Comparing IBW and ABW with actual weight helps in assessing health or nutritional needs, facilitating weight management or clinical decisions. For instance, a higher actual weight than IBW might suggest weight reduction efforts, while ABW can guide adjustments particularly in medical or dietary planning.
