1 gigabyte
Data: 1 GB; definition.
Decimal kB, MB and GB use powers of 1,000. KiB, MiB and GiB use powers of 1,024. The content of a file depends on encoding and compression.
One hour of video
Data: 3.6 GB; example.
A one-hour video at 8 Mbit/s including all streams in the chosen bitrate; overhead ignored.

Why these numbers?
Compare 1 gigabyte with the data size of one hour of video. The notes below explain how each value was chosen.
One hour of video
3.6 GBData · example
A one-hour video at 8 Mbit/s including all streams in the chosen bitrate; overhead ignored.
- Comparing
- Data ↔ Data
- Relative size
- The data size of one hour of video is about 3.6 times 1 gigabyte. The data size of one hour of video is approximately 260% greater than 1 gigabyte.
How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- The data size of one hour of video: This is an illustrative comparison value, not a claim that every example is the same.
Data size depends on encoding and compression; decimal GB and binary GiB are different units.
