How to use the digital storage calculator
Convert between bytes, KB, MB, GB and TB. Enter size in the field above; the megabytes, terabytes, gigabits, bytes are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- GB — Size (GB)
Worked example
With size = 256 GB, the calculator gives megabytes ≈ 262,144 MB; terabytes ≈ 0.25 TB; gigabits ≈ 2,048 Gb; bytes ≈ 2.7488 × 10¹¹.
Frequently asked questions
What is the formula for the digital storage calculation?
Megabytes (MB) = GB × 1024. Terabytes (TB) = GB / 1024. Gigabits (Gb) = GB × 8. Bytes = GB × 1073741824. Here GB is size (GB).
What inputs do I need for the digital storage converter calculator?
You need size in GB. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
