Using Imperial Measurements
Answer:
Square your height in inches. For example if you are 70 inches tall, then multiply 70 by 70. The answer would be 4,900.
Divide weight by height. If you weigh 180 pounds, then divide 180 by 4,900. The answer is 0.03673.
Multiply your last answer by 703. This equals 25.82 so your BMI in this example would be 25.8.
The equation is simply (height^2), (weight/height^2), (Answer*703) = BMI.
