Mbps network speeds, GB/month data plans, KB/s audio bandwidth, they all express the same thing: data/time. How do you convert from one into the other? This bandwidth calculator tool will help you convert from one to the other.
Compare 100 Mbps to bandwidth standards from:Wired network • Internet uplink • Wireless network • Mobile data • Optical media • Peripheral • Monitor • Video bitrates • Cinema bitrates • Hard disk • PCI Express • Memory card • Tape drives •
100 Mbps
Divide by 8. Mbps = megabits per second, MB/s = megabytes per second. 100 Mbps = 12.5 MB/s. Internet speeds are advertised in Mbps (bits), but file sizes are in MB (bytes). 8 bits = 1 byte.
At 100% utilization: 100 Mbps = 12.5 MB/s = 750 MB/min = 45 GB/hour = 1.08 TB/day = 32.4 TB/month. Real usage is much lower - average US household uses 400-600 GB/month.
Bandwidth is the maximum capacity (like a pipe's width). Speed is actual throughput (water flowing through). Your 100 Mbps connection rarely achieves full speed due to latency, congestion, and server limits. Real-world speed is typically 70-90% of bandwidth.
USB 3.0 = 5 Gbps (625 MB/s theoretical). Gigabit Ethernet = 1 Gbps (125 MB/s). USB 3.0 is 5× faster than Gigabit Ethernet on paper, but real-world USB 3.0 achieves ~400 MB/s, while Gigabit Ethernet typically reaches 110 MB/s.
