Mega is a counting unit, which is not commonly used in mathematics, but is very commonly used in many other fields, especially in physics and computer science.

In mathematics, trillions of applications are rare. We seldom use the mathematical figure of trillion to participate in the calculation of various problems and parameters. The mathematical relationship is only 10 million and so on. So, mathematically, one trillion is equal to 1000000.
