Megabits per Second to Terabits per Second (Mbps to Tbps)
1 megabit per second (Mbps) = 0.000001 terabits per second (Tbps). 1 Tbps = 1000000 Mbps. Example: 15 Mbps = 15 × 0.000001 = 0.000015 Tbps.

How to Convert Megabit per Second to Terabit per Second
- 1 Mbps = 0.000001 Tbps
- 1 Tbps = 1000000 Mbps
- Example: convert 15 Mbps to Tbps: 15 Mbps = 15 × 0.000001 Tbps = 0.000015 Tbps
Formula
Tbps = Mbps ÷ 1000000
Derivation from SI units:
- 1 Mbit/s = 10⁶ bit/s.
- 1 Tbit/s = 10¹² bit/s.
- 1 Mbps = 1000000 bps ÷ 1000000000000 bps per Tbps = 0.000001 Tbps
Both units are defined exactly, so the factor is exact. Megabit per Second definition: megabit per second; Terabit per Second definition: terabit per second.
Worked examples
- A reading of 25 Mbps converts to 0.000025 Tbps.
25 Mbps × 0.000001 = 0.000025 Tbps - A value of 200 Mbps is 0.0002 Tbps.
200 Mbps × 0.000001 = 0.0002 Tbps

Frequently asked questions
How many terabits per second are in 1 megabit per second?
1 Mbps = 0.000001 Tbps.
How do I convert megabits per second to terabits per second?
Multiply the value in Mbps by 0.000001, or divide it by 1000000. For example, 15 Mbps × 0.000001 = 0.000015 Tbps.
Is the Mbps to Tbps conversion exact?
Yes. Both units are defined exactly, and 1 Mbps is exactly 0.000001 Tbps.
