Thus far, there is no measure, be it IBW, body mass index (BMI), or any other that can definitively state how much a person should weigh to be healthy. It is highly dependent on each individual. How much a person should weigh is not an exact science. This is why IBW should be considered with the perspective that it is an imperfect measure and not necessarily indicative of health, or a weight that a person should necessarily strive toward it is possible to be over or under your "IBW" and be perfectly healthy. This means that it is possible for highly fit, healthy athletes to be considered overweight based on their IBW. It does not consider the percentages of body fat and muscle in a person's body. Note that IBW is not a perfect measurement. Today, IBW is also used widely throughout sports, since many sports classify people based on their body weight. It has since been determined that the metabolism of certain drugs is more based on IBW than it is total body weight. Although ideal body weight (IBW) today is sometimes based on perceived visual appeal, IBW was actually introduced to estimate dosages for medical use, and the formulas that calculate it are not at all related to how a person looks at a given weight. This is largely due to the perception of an "ideal" body weight, which is often based on what we see promoted through various media such as social media, TV, movies, magazines, etc. Most everyone has at some point tried to lose weight, or at least known somebody who has.

Different styles may be used for each Lat/Long entry, entry of decimal places is not required for the calculator to operate, but all four lat/long boxes must have something entered (even a single zero).Ĥ. Enter Lat/longs in the form: DD.dddddd or DD:MM.mmm or DD:MM:SS.ss, where colons separate degrees, minutes and seconds. Enter Latitude and Longitude for the points at the beginning and end of the leg to be calculated, selecting N/S and E/W as required. You are now ready to make calculations.ģ. Scroll the display so that all of the boxes are on screen with the Lat/Long boxes at the top and the output boxes towards the bottom of the screen.
