"Gigabyte (GB) to Terabyte (TB) Diagram"

Gigabyte (GB) and Terabyte (TB) belong to the same decimal measurement system and are commonly converted when working with digital storage and data sizes.

Follow these steps to derive the conversion factor and formula.

1. Find the source unit (Gigabyte) value in bits

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 GB=1,0003 B×8 =8,000,000,000 bit1\,\mathrm{GB} = 1,000^{3} \,\mathrm{B} \times 8\, = 8,000,000,000\,\mathrm{bit}

2. Find the target unit (Terabyte) value in bits

The Terabyte is a decimal unit. It is defined as 1000^4 bytes, which equals 1000000000000 bytes. Since 1 Byte = 8 bits, multiply the number of Bytes by 8 to express the value in bits.

1 TB=1,0004 B×8 =8,000,000,000,000 bit1\,\mathrm{TB} = 1,000^{4} \,\mathrm{B} \times 8\, = 8,000,000,000,000\,\mathrm{bit}

3. Calculate the Conversion Factor

One Gigabyte is equal to 8000000000 bits, while one Terabyte equals 8000000000000 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).

1 GB1 TB=8,000,000,000 bit8,000,000,000,000 bit=8,000,000,0008,000,000,000,000\dfrac{ 1\,\mathrm{GB} }{ 1\,\mathrm{TB} } = \dfrac{ 8,000,000,000\,\mathrm{bit} }{ 8,000,000,000,000\,\mathrm{bit} } = \dfrac{ 8,000,000,000 }{ 8,000,000,000,000 }

4. Simplify the Fraction

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

8,000,000,0008,000,000,000,000=8,000,000,000÷8,000,000,0008,000,000,000,000÷8,000,000,000=11,000\dfrac{ 8,000,000,000 }{ 8,000,000,000,000 } = \dfrac{ 8,000,000,000\div 8,000,000,000 }{ 8,000,000,000,000\div 8,000,000,000 } = \dfrac{ 1 }{ 1,000 }

5. Decimal Approximation

The exact factor is 1/1000. The decimal result is shown to 30 places or fewer when the division terminates earlier.

11,000≈0.001\dfrac{ 1 }{ 1,000 } \approx 0.001

6. Derive the conversion formula

The conversion factor from Gigabyte (GB) to Terabyte (TB) is 0.001. Therefore, any value in Gigabyte can be converted to Terabyte by multiplying it by this factor.

x GB=x×0.001 TB\boxed{ x\,\mathrm{GB} = x\times 0.001\,\mathrm{TB} }

7. Conversion Formula

Multiply the number of Gigabytes by 0.001 to obtain the equivalent value in Terabytes.

Terabyte=Gigabyte × 0.001\text{Terabyte} = \text{Gigabyte}\ \times\ 0.001

Examples

1. Convert 15 Gigabyte to Terabyte

15 GB=15×0.001=0.015 TB15\ \text{GB} \\ = 15 \times 0.001 \\ = 0.015\ \text{TB}

2. Convert 75 Gigabyte to Terabyte

75 GB=75×0.001=0.075 TB75\ \text{GB} \\ = 75 \times 0.001 \\ = 0.075\ \text{TB}
