The SI prefix "mega" represents a factor of
10^{6}, or in exponential notation, 1E6.

So 1 megaampere = 10^{6} ampere.

In physics, the ampere (symbol: A, often informally abbreviated to amp) is the SI base unit used to measure electrical currents. The present definition, adopted by the 9th CGPM in 1948 is: "one ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed one metre apart in vacuum, would produce between these conductors a force equal to 2 × 10^{-7} newton per metre of length".
