megabit to megabyte Converter
Convert Mb to MB and back with a live reference table.
1 Mb = 0.125 MB\n5 Mb = 0.625 MB\n10 Mb = 1.25 MB\n25 Mb = 3.125 MB\n50 Mb = 6.25 MB\n100 Mb = 12.5 MB
Why this conversion matters
Network speeds often use bits, while downloaded file sizes use bytes, so the divide-by-eight relationship matters. The widget keeps the direction explicit so you can enter either side of the pair without doing the reciprocal by hand. It is built for quick checks where a calculator, specification sheet, recipe, map, or lab note uses the other unit.
For the default example, 100 Mb converts to 12.5 MB. Switching the direction shows the inverse relationship, so 12.5 MB converts back to 100 Mb with the same factor.
Formula and privacy note
The calculation uses 1 Mb = 0.125 MB. Forward conversion multiplies by that factor, and reverse conversion divides by it. Results are rounded to six significant figures for readable estimates, so very small scientific units and large planning units stay scannable. Check the unit labels before copying a result, especially when similar abbreviations appear in the same project. The reference table is generated from the same constant, and everything runs locally in your browser.
Frequently Asked Questions
What factor does this converter use?
It uses the standard factor 1 Mb = 0.125 MB, then applies the reciprocal for the reverse direction.
Why are results rounded?
The main result is rounded to six significant figures so very large and very small values stay readable while preserving the useful precision for quick checks.
Can I convert both directions?
Yes. Choose Mb to MB or MB to Mb from the direction menu and the output updates immediately.
Is this converter private?
Yes. The conversion runs entirely in your browser, and the value you enter is not uploaded or stored.
