How To: Do Celsius to Fahrenheit temperature conversion

The video teaches how to convert degrees Celsius to degrees Fahrenheit. First the boiling points of 32 degrees Fahrenheit and 100 degrees Celsius are plotted on the Y and X axis. Then a line is drawn to join them both. The value m is delta Y (boiling point minus freezing point, i.e., 212-32)/ delta X (boiling point minus freezing point, i.e., 100-0). So m works out to 180/100 or 1.8. Then the formula y=mx+b (intercept of y = 32) is used, substituting X with Celsius and y with Fahrenheit, to c...

How To: Apply the Pythagorean theorem

Meet the Pythagorean theorem—an indispensable tool for any budding geometer. The Pythagorean theorem will allow you to measure the hypotenuse or any other side of a right triangle when the length of its other two sides are known. For specific, step-by-step instructions on how to use this useful formula, usually given as a^2+b^2=c^2, where c^2 is equal to the length of the hypotenuse, watch this free video geometry lesson.

How To: Use Visual Basic to convert temperature units

In this video, we learn how to use Visual Basic to convert temperature units. To start, make two command buttons. After you have created these, make sure you label them. The first command button should say "celsius to fahrenheit" and the second should say "fahrenheit to celcius". After this, make one text box and one label box. Now you will convert celsius to fahrenheit using the formula "F=(9/5*C) + 32". and you will be able to use this to convert temperature units. Save this and use it for ...
