Questions people ask
How do I convert gigabytes to megabytes?
Multiply by 1,000. For example 10 GB = 10,000 MB.
What is the base unit for data?
The converter uses the byte as its internal base. Every unit is converted to bytes and then to the target unit, so any pair of units works.
Where do the conversion factors come from?
From the legal definitions published in NIST Special Publication 811 and the SI Brochure (BIPM). Where a unit is defined exactly, the factor is exact.
