Body mass index calculator downloads
BMI Calculator from http://www.whathealth.com/
BMI Calculator 2
And if you don't want to download the calculators here is a cool chart from the CDC.
|Category||BMI range - kg/m2||BMI Prime||Mass (weight) of a 1.8 metres (5 ft 11 in) person with this BMI|
|Severely underweight||less than 16.5||less than 0.66||under 53.5 kilograms (8.42 st; 118 lb)|
|Underweight||from 16.5 to 18.5||from 0.66 to 0.74||between 53.5 and 60 kilograms (8.42 and 9.45 st; 118 and 132 lb)|
|Normal||from 18.5 to 25||from 0.74 to 1.0||between 60 and 81 kilograms (9.4 and 13 st; 130 and 180 lb)|
|Overweight||from 25 to 30||from 1.0 to 1.2||between 81 and 97 kilograms (12.8 and 15.3 st; 180 and 210 lb)|
|Obese Class I||from 30 to 35||from 1.2 to 1.4||between 97 and 113 kilograms (15.3 and 17.8 st; 210 and 250 lb)|
|Obese Class II||from 35 to 40||from 1.4 to 1.6||between 113 and 130 kilograms (17.8 and 20.5 st; 250 and 290 lb)|
|Obese Class III||over 40||over 1.6||over 130 kilograms (20 st; 290 lb)|
|BMI = |
( kg/m² )
|(weight in pounds * 703 )|
|height in inches²|
|BMI = |
( kg/m² )
|weight in kilograms|
|height in meters²|
Generally when I'm not working out by this chart I'm stuck in the Obese Class I category, but when I'm at about 200 lbs I'm still considered overweight. The funny thing is at 200 lbs I'm sporting a six pack. So whats the deal? I think the pros of a body mass index is that it can give you an indication of your general physical state but the con is that it doesn't work for everyone and I think that's most everyone. As a general rule of thumb I think I'll stick with the tape measure, my blood pressure and resting pulse rate for a more accurate indication. Besides all that it is kinda fun to play with.

Keep your computer updated with the latest patches. If you don’t know how to do this, have someone help you set your system to update itself.
Don’t use “free” security scans that pop up on many web sites. All too often these are fake, using scare tactics to try to get you to purchase their “full” service. In many cases these are actually infecting you while they run. There is reason to believe that the creators of the Conficker worm are associated with some of these fake security products.
Turn off the “autorun” feature that will automatically run programs found on memory sticks and other USB devices.
Be smart with your passwords. This includes Change your passwords periodically
Use complex passwords – no simple names or words, use special characters and numbers
Using a separate, longer password for each site that has sensitive personal information or access to your bank accounts or credit cards.
If you have a computer that is infected, you will need to use an uninfected computer to download a specialized Conficker removal tool from. The tool is available here.
