Mb to Gb Conversion Formula
Here's the exact Mb to Gb formula in copy-paste-ready form — multiply by 0.001 to go from megabits to gigabits, or by 1,000 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert Mb to Gb
Gb = Mb × 0.001
// Reverse: Convert Gb to Mb
Mb = Gb × 1,000
