Lesson4:Fund Me(doubt)

Why did we take minUSD as 5e18 initially because the getConversionRate is already giving the value in uint256 as the real value of eth in USD (as we are dividing by 1e18 already in the code)??
Why can't we take minUSD as 5 simply??

Let's take some values as an example.

If you call the function getConversionRate passing 0.01 for ethAmount, ethPrice will be 3810e18 (current price) and ethAmountInUsd will be (ethPrice * ethAmount) / 1000000000000000000 = 3810e18 * 0.01e18 / 1e18 = 38.1e18 and the minimum USD amount is 5e18.

Thanks a lot, I didn't considered eth amount in wei .
As, the amount in msg.value is always in wei.
