If you use pounds in a BMI calculation, you must multiply the pounds by 703
You can see the formula here:
http://www.whathealth.com/bmi/formula.html Oh, I read the question wrong, why is 703 used? They must have figured out BMI for metric first and then divided the metric BMI by the number they got using imperial units, which would be 703. Then just multiply 703 into their formula.
Because it is the conversion factor of the BMI forlmula.
129 lbs and 5'5" gives a BMI of 21.47 which is normal.The normal weight range of the given heigh is 111 - 150 lbs.Please see the related link for the calculation.
BMI=(weight in lbs*703)/(height in inches^2) (weight in pounds multiplied by 703) divided by (height in inches squared)
In SI Units: BMI = kg/m2In Imperial Units: BMI = lb*703/in2 or l*4.88/ft2PS: I love SI Units. I use them all the time.
To determine your ideal weight use the BMI calculator. These can be found online, but there is a simple equation to determining your own BMI. BMI stands for body mass index. This will give you a number to aim for so you are sure you are at a healthy weight for your current height. BMI = ((Your weight in pounds) / (Height in inches x Height in inches)) x 703 So, take your weight in pounds, divide that by your height in inches squared, and multiply your total by 703. This will give you a number, which is your BMI. A healthy BMI is between 18.5 and 24.9. If your BMI is below 18.5, you are underweight for your height. If your BMI is between 25 and 29.9 you are considered overweight. If your BMI is above 30, you are considered obese. BMI = (Weight in Pounds (Height in inches) x (Height in inches)) x 703
Use your BMI or Body Mass Index. The equation is: BMI = 704 x weight (in lbs)/height in inches squared So, that's BMI = 704 times your weight in pounds, divided by your height in inches squared A healthy number is between 19 and 25.
it all depends on your bmi which is calculated by: BMI=(weight in pounds)*703/(height in inches)^2 Example: (188)*703/(67)^2=29.44175 HOW TO READ YOUR BMI: {| ! BMI |- ! Weight Status | Below 18.5 Underweight 18.5 -24.9 Normal 25 - 29.9 Overweight 30 & Above Obese SO 29.44 WOULD BE OVERWEIGHT. hope this helped |}
It depends on your height and your gender. A BMI calculation is a good indicator.
Use a BMI calculation as your starting point.
One can find a BMI calculation tool on the Web MD website. It allows one to calculate their body mass index and find out if they are overweight. One can also be found on the NHS website in the UK.
BMI = pounds * 703/height in inches squared = 100 lb * 703/(56 in)^2 = 22.4 You are in the proper range of 19 to 25.
One way to determine if you are over weight is to determine your Body Mass Index (BMI), which is recommended to be no more than 30. To calculate your BMI, use the following formula: Divide your weight by your height2 (71 squared), then multiply by 703. For example: If you are 5'11 and weigh 205 lbs., you would divide 205 by 5,041, then multiply by 703, which would give you a BMI of 28.59. So by this method, then no, you are not overweight.
