This converter turns megabits into terabytes instantly, using the exact factor 1 megabit = 1.25e-07 terabytes. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
One million bits — how internet speeds are advertised. One trillion bytes; standard hard-drive capacity.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
megabits- The amount you are converting, measured in megabits
1.25e-07- The exact number of terabytes in one megabit
terabytes- The converted result
How it works, step by step
- Enter the number of megabits you want to convert.
- The value is multiplied by 1.25e-07, the exact conversion factor.
- The result is displayed in terabytes, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 megabits
Multiply 5 by 1.25e-07. That gives 6.2500e-07 terabytes. A quick sanity check: one megabit is smaller than one terabyte, so the number should get smaller — and it does.
Converting 72 megabits
72 × 1.25e-07 = 0.000009 terabytes. Working backwards, 0.000009 ÷ 1.25e-07 returns 72 megabits, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many terabytes are in one megabit?
Exactly 1.25e-07. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert megabits to terabytes?
Terabytes = megabits × 1.25e-07. To reverse it, divide instead: megabits = terabytes ÷ 1.25e-07, which is the same as multiplying by 8000000.
Is the megabit bigger than the terabyte?
No. One megabit is only 1.25e-07 of a terabyte, so the terabyte is the larger unit.
Why does my answer differ slightly from other megabits to terabytes converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
What is a megabit?
