Megabits to petabit Conversion
1 megabits (Mb) is equal to 0.000000001 petabit (Pbit).
1 Mb = 0.000000001 Pbit
or
1 Pbit = 1000000000 Mb
Formula
To convert a digital storage from megabits (Mb) to petabit (Pbit), divide the digital storage in megabits by 1000000000
d(Pbit) = d(Mb) / 1000000000
Examples:
Convert 1 megabits to petabit:
d(Pbit) = 1Mb / 1000000000 = 0.000000001 Pbit
