World Currency Unit (WCU) is a type of imaginary money that people use to compare the value of different types of real money from all over the world. It's kind of like a special ruler that helps you measure how long or short things are, but instead of length, it measures the value of money.
Imagine you have a toy car and a toy truck. You want to know which one is worth more, so you use a special tool called a scale. The scale can help you figure out which toy weighs more than the other. The WCU is just like a scale, but it helps people compare different types of money from different countries.
So, let's say you're traveling to a different country and you want to buy something. You'll have to exchange your money for the local currency of the country you're visiting. For example, if you're from the United States and you're traveling to Japan, you'll have to exchange your US dollars for Japanese yen. But how do you know if you're getting a fair deal? This is where the WCU comes in handy.
The WCU can tell you how much your US dollars are worth compared to Japanese yen (or any other currency you're exchanging). It's like a universal standard that everyone can use to compare currencies. So, if the WCU tells you that 1 US dollar is worth 110 Japanese yen, then you know you're getting a fair exchange rate.
Overall, the World Currency Unit is a tool that helps people compare the value of different types of money from all over the world, making it easier to exchange money and know if you're getting a good deal.
