What is the procedure for calculating BMI? What does it tell?
BMI is your height divided by your weight and indicates if your weight is in an underweight, healthy, overweight or obese range for your height. This is a general screening test and not a comprehensive diagnostic test — if you have any particular health concerns, it may be advisable to talk to your doctor about your results.
Will the Age Calculator calculate leap years?
Yes, it will determine your actual age using the real calendar, including leap years, so it's as accurate as the day.
The Percentage Calculator can do what?
It does the common percentage calculation which people need — what percentage is one number of another, what is the percentage increase or decrease and what is a percentage of a total.
Can you use the Sales Tax Calculator with any tax rate?
Yes — you can add in the price and any applicable tax rate based on where you are, and the calculator calculates the total, or you can input the total and it will calculate the pre-tax price.
