Which of the following is the correct formula for calculating Body Mass Index (BMI)?

Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person. The formula is defined as body mass divided by the square of the body height, universally expressed in units of ${\text{kg/m}}^2$:
$$\text{BMI}=\frac{\text{Weight in kilograms}}{(\text{Height in meters}{)}^2}$$
