Mb to GB Converter

The Megabit is a decimal unit. It is defined as 1000^2 bits, which equals 1000000 bits.

$1\,\mathrm{Mb} = 1,000^{2} \,\mathrm{bit} = 1,000,000\,\mathrm{bit}$

The Gigabyte is a decimal unit. It is defined as 1000^3 bytes, which equals 1000000000 bytes. Since 1 Byte = 8 bits, multiply the number of Bytes by 8 to express the value in bits.

$1\,\mathrm{GB} = 1,000^{3} \,\mathrm{B} \times 8\, = 8,000,000,000\,\mathrm{bit}$

One Megabit is equal to 1000000 bits, while one Gigabyte equals 8000000000 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).

$\dfrac{ 1\,\mathrm{Mb} }{ 1\,\mathrm{GB} } = \dfrac{ 1,000,000\,\mathrm{bit} }{ 8,000,000,000\,\mathrm{bit} } = \dfrac{ 1,000,000 }{ 8,000,000,000 }$

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

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

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 Megabit (Mb) to Gigabyte (GB) is 0.000125. Therefore, any value in Megabit can be converted to Gigabyte by multiplying it by this factor.

$\boxed{ x\,\mathrm{Mb} = x\times 0.000125\,\mathrm{GB} }$

Multiply the number of Megabits by 0.000125 to obtain the equivalent value in Gigabytes.
