64M * 1 reasonable to remove the M from the 64?

Hello. I have written a script to calculate the number of sectors per
cylinder, blocks, and bytes on a compact flash card. These lines are
used to get input from a user:

my $megs = param("p0");
---
print p('Enter size of card (16, 32, 64, 128, 256) in M here: ');
print start_form(), textfield("p0", "", "4", "4");
print submit("Click to calculate"), end_form();

The variable holding the value entered is $megs. In case someone
(reasonably) enters (e.g.) 64M instead of 64, I say farther down:

$megs *= 1;

Then I check $megs using == against the valid numerical entries. I
don't get any errors in the logs, but yet this just feels too easy.
Maybe it's what makes Perl fun?
