Question 3

How accurate is the gb to mb converter on Toolhub?

Accepted Answer

The gb to mb converter on Toolhub uses the exact SI-defined conversion factors where applicable (e.g. 1 inch = 25.4 mm exactly). For non-metric units like miles, gallons, and pounds, we use the internationally agreed conversion factors published by NIST (National Institute of Standards and Technology). Results are accurate to 6+ decimal places, far beyond what any practical use case requires.
