Unit 128 Inches and Centimeters

B : Hi, Julie.

I'm trying to figure out the dimensions of this MP4 player I want to buy, but I'm having trouble converting these English measurements. You're really good at mathematics, aren't you? It says that the MP4 player is 3.6 inches tall and two inches wide, but what does that mean in centimeters? G : Well, according to my math book, one inch equals 2.54 centimeters, so to convert that, we need to multiply each English measurement by that number.

Wait, I have a calculator in my pocket. B : Great!

G : According to the calculator, that would make it 9.1 centimeters tall and, let's see, about five centimeters wide.

B : So, its height is about nine centimeters and its width is about five centimeters, but what about its weight?

The website says that it weighs 3.6 ounces. G : We multiply 3.6 by 28.3, which is the equivalent in grams, and that converts to about 102 grams.

B : All right then, the MP4 player is about nine centimeters tall and five centimeters wide, and weighs about 102 grams.

I thought it would have to have larger dimensions to be able to hold 5,000 songs, but it's small and light! Do you think I should buy it, Julie? G : It sounds like a good product, but it depends on the price.

B : Well, now I have the same sort of problem again.

Could you help me figure out how to convert Chinese currency to our currency?
