Why Use the Bandwidth Converter
- Bits vs bytes — correctly handles the 8x difference between bits and bytes
- Download time calculator — estimate transfer times for any file size and speed
- Required bandwidth — calculate what speed you need for specific use cases
- SI vs binary — clearly distinguishes decimal and binary prefix systems
- Legacy units — converts T1, T3, OC-x and other legacy network speeds
Use the Bandwidth Converter at TechConverter.me to plan network capacity, estimate download times, and convert between any bandwidth units accurately.
Examples
Example 1: Common Bandwidth Conversions
1 Gbps (gigabit per second) =
1,000 Mbps
1,000,000 Kbps
125 MB/s (megabytes per second)
125,000 KB/s
100 Mbps (typical home internet) =
12.5 MB/s
100,000 Kbps
Note: 1 byte = 8 bits
ISPs advertise in Mbps (megabits)
File sizes are in MB (megabytes)
Always divide by 8 to convert Mbps → MB/s
Example 2: Download Time Calculator
File size: 4 GB (movie download)
Connection: 100 Mbps
Calculation:
4 GB = 4 × 1024 MB = 4,096 MB = 32,768 Mb (megabits)
Time = 32,768 Mb / 100 Mbps = 327.68 seconds = ~5.5 minutes
With 80% efficiency (real-world overhead):
Actual time ≈ 6.8 minutes
File size: 1 TB (cloud backup)
Connection: 100 Mbps
Time: ~22 hours (ideal) / ~28 hours (real-world)
Example 3: Required Bandwidth for Streaming
Video streaming requirements:
SD (480p): 3 Mbps
HD (720p): 5 Mbps
FHD (1080p): 8 Mbps
4K (2160p): 25 Mbps
4K HDR: 35 Mbps
Audio streaming:
MP3 128 kbps: 0.128 Mbps
MP3 320 kbps: 0.320 Mbps
Lossless: 1-5 Mbps
Video conferencing:
720p call: 1.5 Mbps up + 1.5 Mbps down
1080p call: 3.0 Mbps up + 3.0 Mbps down
