How long is 8 cm in inches?

Answer 1

Rather than giving you a one shot answer, I'm encouraging you to learn how to do unit conversions. The basic conversion is 1 inch = 2.54 centimeters exactly. So now you can write two different forms of "1"
First, (1 inch)/(2.54 cm) = 1, and (2.54 cm)/1(inch) = 1. Next, whenever you multiply some "thing" by 1 you haven't changed the "thing". Which form of 1 do you use? Use the form that has puts the new unit in the numerator and the old unit in the denominator. Then multiply. I'll use a "thing" different from your specific number: 13.75 inches.

13.75 inches X (2.54 cm)/(1 inch) = 34.925 cm. inches/inch. But inches/inch = 1, so we have 34.925 cm. Now try it out on your own number and see if these other guys are telling the truth. :)

If you learn this technique, you can do all the conversions you want given 1 basic relationship.
