Terabits per Second to Megabits per Second (Tbps to Mbps)
1 terabit per second (Tbps) = 1000000 megabits per second (Mbps). 1 Mbps = 0.000001 Tbps. Example: 15 Tbps = 15 × 1000000 = 15000000 Mbps.

How to Convert Terabit per Second to Megabit per Second
- 1 Tbps = 1000000 Mbps
- 1 Mbps = 0.000001 Tbps
- Example: convert 15 Tbps to Mbps: 15 Tbps = 15 × 1000000 Mbps = 15000000 Mbps
Formula
Mbps = Tbps × 1000000
Derivation from SI units:
- 1 Tbit/s = 10¹² bit/s.
- 1 Mbit/s = 10⁶ bit/s.
- 1 Tbps = 1000000000000 bps ÷ 1000000 bps per Mbps = 1000000 Mbps
Both units are defined exactly, so the factor is exact. Terabit per Second definition: terabit per second; Megabit per Second definition: megabit per second.
Worked examples
- A reading of 1 Tbps converts to 1000000 Mbps.
1 Tbps × 1000000 = 1000000 Mbps - A value of 50 Tbps is 50000000 Mbps.
50 Tbps × 1000000 = 50000000 Mbps

Where it's used
Terabits per Second are used for undersea fibre cables, while megabits per second appear in internet plans and speed tests. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many megabits per second are in 1 terabit per second?
1 Tbps = 1000000 Mbps.
How do I convert terabits per second to megabits per second?
Multiply the value in Tbps by 1000000. For example, 15 Tbps × 1000000 = 15000000 Mbps.
Is the Tbps to Mbps conversion exact?
Yes. Both units are defined exactly, and 1 Tbps is exactly 1000000 Mbps.
