PB to MB Converter

The Petabyte is a decimal unit. It is defined as 1000^5 bytes, which equals 1000000000000000 bytes. Since 1 Byte = 8 bits, multiply the number of Bytes by 8 to express the value in bits.

$1\,\mathrm{PB} = 1,000^{5} \,\mathrm{B} \times 8\, = 8,000,000,000,000,000\,\mathrm{bit}$

The Megabyte is a decimal unit. It is defined as 1000^2 bytes, which equals 1000000 bytes. Since 1 Byte = 8 bits, multiply the number of Bytes by 8 to express the value in bits.

$1\,\mathrm{MB} = 1,000^{2} \,\mathrm{B} \times 8\, = 8,000,000\,\mathrm{bit}$

One Petabyte is equal to 8000000000000000 bits, while one Megabyte equals 8000000 bits. The conversion factor is obtained by dividing the value of 1 source unit (in bits) by the value of 1 target unit (in bits).

$\dfrac{ 1\,\mathrm{PB} }{ 1\,\mathrm{MB} } = \dfrac{ 8,000,000,000,000,000\,\mathrm{bit} }{ 8,000,000\,\mathrm{bit} } = \dfrac{ 8,000,000,000,000,000 }{ 8,000,000 }$

The fraction can be simplified by dividing both the numerator and denominator by 8,000,000, giving the exact conversion factor.

$\dfrac{ 8,000,000,000,000,000 }{ 8,000,000 } = \dfrac{ 8,000,000,000,000,000\div 8,000,000 }{ 8,000,000\div 8,000,000 } = \dfrac{ 1,000,000,000 }{ 1 }$

The exact factor is 1000000000/1. The decimal result is shown to 30 places or fewer when the division terminates earlier.

$\dfrac{ 1,000,000,000 }{ 1 } \approx 1000000000$

The conversion factor from Petabyte (PB) to Megabyte (MB) is 1000000000. Therefore, any value in Petabyte can be converted to Megabyte by multiplying it by this factor.

$\boxed{ x\,\mathrm{PB} = x\times 1000000000\,\mathrm{MB} }$

Multiply the number of Petabytes by 1,000,000,000 to obtain the equivalent value in Megabytes.
