The workbook in the above folder allows you to calculate someone's BMI (body mass index) from imperial measurements:

You could type your name into C2 if you want to use your data

Note that the workbook contains a module containing some built-in constants, to make life easier:

Although you know there are 12 inches in a foot, it makes for clearer coding if you use constants instead

Write as many of the following functions to go in the pink cells shown above as you have time for:

• A function to turn inches and feet into metres, to be used to calculate cell C7
• A function to turn stones and pounds into kilograms, to be used to calculate the figures in column E
• A function to turn height in metres and weight in kilograms into Body Mass Index, using the formula (Weight in kilograms) / (Height in metres squared)

As a guideline, your BMI should be about 20-25.  Anything over 25 is considered overweight.

Save this workbook as BMI, and close it down.
