MBps Vs Mbps

In hindi -What is difference between MBps and Mbps

Compare MBps and Mbps

8 bits = 1 byte

1000 bytes = 8 kilobits (Kb) = 1 Kilobyte (KB)

1000 Kilobytes (KB) = 8 Mbps = 1 MBps

Mbps (Small "b") vs MBps (Capital "B")

Mbps: - megabit per second (Mbit/s or Mbps) डेटा ट्रांसफर की एक यूनिट होती है जो की 1,000,000 bits per second or 1,000 kilobits per second के बराबर होती है| 8 Megabits per second, 1 Megabyte per second (ie. 8 Mbps = 1 MBps) के बराबर होती है |
