This page converts terabits per second into megabits per second using the factor 1,000,000, and shows the reverse figure alongside it. Both units measure how much data moves per second, which is why one number does the whole job.
Megabits per second is how every broadband package is advertised. The figure is bits, so divide by eight to get the download speed your browser will show. Terabits per second describes backbone and submarine cable capacity rather than anything you can buy for a house.
Bits and bytes. Network speeds are sold in bits per second and file transfers are reported in bytes per second, and there are eight bits to a byte, so a 100 Mbps line downloads at about 12 MB/s. A connection is not underperforming by a factor of eight; it is being measured in different units. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into megabits per second, which is usually more useful than the bare number.
The formula
terabits per second- The amount you are converting, in terabits per second
1,000,000- The exact number of megabits per second in one terabit per second
megabits per second- The converted result
How it works, step by step
- Enter the value in terabits per second.
- It is multiplied by 1,000,000, the exact factor between the two units.
- The answer is shown in megabits per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Wi-Fi 6 link rate: 0.0012 Tbit/s in megabits per second
Take wi-fi 6 link rate, roughly 0.0012 Tbit/s. The conversion is a single multiplication — 0.0012 × 1e+06 — giving 1200 Mbit/s. Because the relationship is proportional, doubling the input doubles the answer to 2400 Mbit/s.
Wired gigabit Ethernet: 0.001 Tbit/s in megabits per second
At 0.001 Tbit/s (wired gigabit ethernet), the same quantity in megabits per second is 0.001 × 1e+06 = 1000 Mbit/s. One terabit per second is 1e+06 megabits per second, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many megabits per second are in one terabit per second?
Exactly 1,000,000. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert terabits per second to megabits per second?
megabits per second = terabits per second × 1,000,000. Reversed, terabits per second = megabits per second ÷ 1,000,000, which is the same as multiplying by 1e-06.
Which is the bigger unit, the terabit per second or the megabit per second?
The terabit per second. One terabit per second equals 1e+06 megabits per second.
What does this quantity actually measure?
Both units measure how much data moves per second. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a terabit per second?
Terabits per second describes backbone and submarine cable capacity rather than anything you can buy for a house.
What is a megabit per second?
Megabits per second is how every broadband package is advertised. The figure is bits, so divide by eight to get the download speed your browser will show.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
