What is the formula for calculating BMI?
What is the formula for calculating BMI?
The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.
What is ISA condition?
The International Standard Atmosphere (ISA) is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth’s atmosphere change over a wide range of altitudes or elevations.
What ISA temperature deviation?
n the rate of change in temperature in a given direction, esp. in altitude. temperature-humidity index.
What is ISA temperature?
In the ISA model, the standard sea level pressure/temperature is 29.92 in. (1,013.25 mb) and 59°F (15°C). As atmospheric pressure decreases with height, the temperature will decrease at a standard lapse rate.
How do you calculate BMI with height and weight?
With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Since height is commonly measured in centimeters, an alternate calculation formula, dividing the weight in kilograms by the height in centimeters squared, and then multiplying the result by 10,000, can be used.
How is ISA calculated?
To find ISA standard temperature for a given altitude, here’s a rule of thumb: double the altitude, subtract 15 and place a – sign in front of it. (For example, to find ISA Temp at 10,000 feet, we multiply the altitude in thousands by the 2C/1000 ft to get 20 [10 (thousands) x 2 (degrees C) = 20C (temp change)].
How is ISA deviation calculated?
ISA temperature deviation is the difference between the actual temperature and the ISA temperature for certain altitude.
- Formula of the ISA temperature at certain altitude: 15 – [(height/1000) x 2] °C.
- Formula of the ISA temperature deviation at certain altitude: Actual temperature – ISA temperature.

How do I calculate ISA?
What does ISA 15 mean?
RE: ISA – International Standard Atmosphere At sea level, it’s 15C and a pressure of 29.92. Naturally, as you increase in altitude *above* sea level, the temperature will decrease, as will the pressure.
What is the BMI for 165 cm?
Ideal Body Mass Based on BMI
| height (cm) | minimum weight (BMI=20) | obesity (BMI=30) |
|---|---|---|
| 163 | 53.1 | 79.7 |
| 164 | 53.8 | 80.7 |
| 165 | 54.5 | 81.7 |
| 166 | 55.1 | 82.7 |
How to calculate the temperature deviation from ISA?
Using our example, to calculate the deviation from ISA: 6°C (actual OAT at 8000ft) -1°C (ISA temperature at 8000ft) = Deviation of +7°C. This means that the temperature is 7 °C warmer than the given ISA temperature for that altitude.
What is the ISA deviation for a cruise?
ISA deviation = OAT – ISA temperature for the height. ISA = 15 – 1.98 * Hp/1000. but we normally use 2 in lieu of 1.98. e.g. planned cruise at pressure height (Hp) 3000 ft. Forecast OAT is 20C.
How to calculate BMI for height and weight?
Calculating BMI Using the English System Formula: weight (lb) / [height (in)]2 x 703 Calculation: [weight (lb) / height (in) / height (in)] x 703
How do you calculate your body mass index?
Calculate Your Body Mass Index. Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. Enter your weight and height using standard or metric measures. Select “Compute BMI” and your BMI will appear below. .
