This section provides detailed instructions on how to effectively create a BMI Calculator using the Nested Calculated Fields

Building a BMI Calculator with Nested Calculated Fields

Step-by-Step Guide:

  1. Introduction:

    • The tutorial starts with an overview of using Calculated Fields within Calculated Fields to build a BMI calculator. This method involves converting user-inputted weight and height into BMI.

  2. Gathering User Inputs:

    • Users are prompted to enter their weight in kilograms and their height in feet and inches through number fields and dropdowns.

  3. Converting Units:

    • Weight Conversion: A Calculated Field converts the weight from kilograms to pounds using the conversion rate (1 kg = 2.2 pounds).
    • Height Conversion: Another Calculated Field converts the height from feet and inches to total inches.

  4. Calculating BMI:

    • A final Calculated Field calculates the BMI using the formula: [weight in pounds]/([height in inches]^2)×703.
    • The tutorial provides detailed instructions on setting up these calculations within the form builder.

  5. Enhancing User Experience:

    • To streamline the user interface, intermediate calculations (weight in pounds and height in inches) are hidden from the user.
    • The final output, BMI, is displayed in a user-friendly format, ensuring that the calculations are transparent and the interface remains clean.

  6. Publishing and Testing:

    • The form is published, and the tutorial demonstrates entering data to showcase the BMI calculation in action.
    • Tips on hiding calculation fields from the user view to keep the form simple and focused on the end result are also provided.
