Tb to PB Converter

The Terabit is a decimal unit. It is defined as 1000^4 bits, which equals 1000000000000 bits.

$1\,\mathrm{Tb} = 1,000^{4} \,\mathrm{bit} = 1,000,000,000,000\,\mathrm{bit}$

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.

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

One Terabit is equal to 1000000000000 bits, while one Petabyte equals 8000000000000000 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).

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

The fraction can be simplified by dividing both the numerator and denominator by 1,000,000,000,000, giving the exact conversion factor.

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

The exact factor is 1/8000. The decimal result is shown to 30 places or fewer when the division terminates earlier.

$\dfrac{ 1 }{ 8,000 } \approx 0.000125$

The conversion factor from Terabit (Tb) to Petabyte (PB) is 0.000125. Therefore, any value in Terabit can be converted to Petabyte by multiplying it by this factor.

$\boxed{ x\,\mathrm{Tb} = x\times 0.000125\,\mathrm{PB} }$

Multiply the number of Terabits by 0.000125 to obtain the equivalent value in Petabytes.
