WebNov 4, 2024 · Body Mass Index. BMI is a tool that has been used by health professionals to assess body fatness and health. 5 It’s a mathematical equation that compares your weight to your height. BMI = (weight in pounds)/ (height squared) X 703. For example: (150 pounds)/ (66 inches x 66 inches) X 703 = 24. WebThere are an infinite number of values between any two values. And differences between any two values are always meaningful. Typically, you measure continuous variables on a scale. Examples of continuous data include height, weight, and temperature. Statisticians divide continuous data into two types that you measure using interval and ratio ...
WebJan 11, 2024 · 1. Know that F (force) = m (mass) * a (acceleration). [3] This simple equation is what you'll use to convert weight into mass (or mass into weight, if you want to). Don't be worried about what the letters mean — we'll tell you: Force is the same thing as weight. Use Newtons (N) as weight.
