What is a BMI Calculator?

  • A BMI calculator is an online or offline device that measures your body mass index. 
  • The body mass index or BMI is a measure of how much body mass you have in relation to your height and weight.
  • Body mass refers not only to the fat within your body but also to muscles and bones. 
  • It is calculated by taking your weight and dividing it by the square of your height. 
  • The BMI figures let you know whether you are within the normal weight range, or if you are underweight or overweight.
  • Both high BMIs and low ones are known to raise a host of health problems, especially as you age. 
  • However, a high BMI in itself is not always, medically speaking, a cause for alarm. It should be viewed in conjunction with other health parameters.

How do you calculate total body water?

Formula For Calculating Total Body water for male and female are :

  • Male TBW = 2.447 - (0.09156 x age) + (0.1074 x height) + (0.3362 x weight)
  • Female TBW = -2.097 + (0.1069 x height) + (0.2466 x weight)

What temp is C to F?

To convert a temperature from Celsius (°C) to Fahrenheit (°F), use the following formula:

(°C x 9/5) + 32 = °F

 

This formula involves multiplying the temperature in Celsius by 9/5 and then adding 32 to the result to get the temperature in Fahrenheit.

For example, to convert 20°C to Fahrenheit:

(20 x 9/5) + 32 = 68°F

 

Therefore, 20°C is equal to 68°F.

How do you convert km to speed?

Kilometers (km) is a unit of distance, not speed. However, you can convert kilometers per hour (km/h) to other units of speed. Here's how to convert km/h to some other common units of speed:

  1. To convert km/h to meters per second (m/s), divide the value in km/h by 3.6. For example, 60 km/h is equivalent to 16.67 m/s (60 ÷ 3.6 = 16.67).

  2. To convert km/h to miles per hour (mph), multiply the value in km/h by 0.6214. For example, 60 km/h is equivalent to 37.28 mph (60 × 0.6214 = 37.28).

  3. To convert km/h to feet per second (ft/s), multiply the value in km/h by 0.9114. For example, 60 km/h is equivalent to 54.68 ft/s (60 × 0.9114 = 54.68).

These formulas can be used to convert any value in kilometers per hour to the desired unit of speed.

How do you calculate pressure conversion?

  • To calculate pressure conversion, you need to know the conversion factor between the two units of pressure you want to convert.
  • For example, if you want to convert atmospheres (atm) to kilopascals (kPa), you would use the conversion factor 1 atm = 101.3 kPa.
  • Once you know the conversion factor, you can simply multiply the value in the initial unit by the conversion factor to get the value in the desired unit.
  • For example, if you want to convert 2 atm to kPa, you would multiply 2 by 101.3 to get 202.6 kPa.
  • Here is the general formula for converting pressure from one unit to another:

Value in desired unit = Value in initial unit x Conversion factor

  • It's important to remember that when converting between units, you should also consider the appropriate significant figures and rounding rules.
  • Additionally, some conversion factors may be exact while others may have some degree of approximation, so be sure to use the most accurate conversion factor available for your calculation.

How do you calculate blood volume?

You can calculate blood volume using a blood volume calculator or you can use this Nadler's formula:

1. Nadler's Equation

  • For Males

BV = 0.3669 × h³ + 0.03219 × w + 0.6041

 

  • For Females

BV = 0.3561 × h³ + 0.03308 × w + 0.183

 

2. Lemmens-Bernstein-Brodsky equation

BV = Weight × 70 / √(BMI / 22)

What is a good fuel economy?

A good fuel economy is a relative term and can depend on several factors, such as the type of vehicle, the driving conditions, and the fuel type. Here is a table showing the fuel economy ratings for cars based on EPA ratings in the United States:

 

Fuel Economy Rating (MPG) Classification
Less than 15 Poor
15 - 20 Fair
21 - 25 Good
26 - 30 Very Good
31 - 40 Excellent
41 and above Outstanding

 

Note that these ratings are based on standardized tests and may not accurately reflect real-world driving conditions or individual driving habits. Additionally, fuel economy can vary based on the type of vehicle and the fuel type used. Therefore, it's important to consider other factors, such as the cost of fuel and the environmental impact, when evaluating the fuel economy of a vehicle.

What is a normal absolute eosinophil count?

In peripheral blood, an absolute eosinophil count (determined by multiplying the total WBC count by the percentage of eosinophils) of 0 to 500 cells/microL (<0.5 x 109/L) is typically considered normal.
