PayBackTime
|
|
|
Ever wondered how long it will take to pay off your credit card with those minimum payments? PayBackTime will tell you! This script is focused on determining how long it will take to pay off a loan or credit card, given a minimum payment, balance, and interest rate. The results will show the time it will take to pay off the balance with that monthly payment, number of payments, and the total interest the user will end up paying. For illustration purposes, it also shows the same data based on a bi-weekly payment of half the amount of the monthly payment.

The Fluid Flow Calculator
|
|
|
This calculator is used to calculate pipe friction losses for straight piping handling water and water with varying percentages of ethylene glycol. The calculator uses an algorithm developed from the basic principles of fluid mechanics. This calculator allows the user to input the fluid type, the fluid temperature, the flow rate, the pipe size, pipe length, and pipe material. The calculator then determines the velocity, the Reynolds number, the Moody friction factor, the pipe friction factor, the pipe head loss, and the pipe friction loss in PSI.

SFEBMIcalc
|
|
|
SFEBMICalc is a simple Body Mass Index calculator. If a user enters their height (in centimeters or inches) and their weight (in kilograms or pounds), the program will return their Body Mass Index. You can configure it so that either Pounds/Inches or Kilograms/Centimeters is the default, and even change the spelling of Centimeters if you like.

Fatalyzer
|
|
|
This CGI script allows your visitors to calculate their percentage of body fat based on various skinfold measurements. This is a great way to add content to your health or fitness web site. The accuracy of skinfold bodyfat testing is largely based on the accuracy of the measurements and calipers are recommended.
