Bandwidth Converter
Convert between Mbps, MB/s, Gbps, and more. Calculate real download speeds and times.
bits (Mbps), while file sizes use bytes (MB). There are 8 bits in 1 byte, so 100 Mbps = 12.5 MB/s.
Mbps (megabits), but downloads show MB/s (megabytes). Divide your advertised speed by 8 to get real download speed.
📖 Understanding Bandwidth Units
Internet speed can be confusing because ISPs use bits while your computer shows bytes. This converter helps you understand your real download speeds.
Common Conversions
- 100 Mbps = 12.5 MB/s (typical fiber internet)
- 1 Gbps = 125 MB/s (gigabit internet)
- 50 Mbps = 6.25 MB/s (standard broadband)
- 25 Mbps = 3.125 MB/s (basic streaming)
Unit Reference
- bps: Bits per second (base unit)
- Kbps: Kilobits per second (1,000 bps)
- Mbps: Megabits per second (1,000,000 bps)
- Gbps: Gigabits per second (1,000,000,000 bps)
- MB/s: Megabytes per second (8 Mbps)
💡 Pro Tip: To quickly estimate MB/s from Mbps, divide by 8. So 100 Mbps ÷ 8 = 12.5 MB/s. This is your actual download speed in most programs.
❓ Frequently Asked Questions
Your ISP advertises speed in megabits (Mbps), but downloads show megabytes (MB/s). There are 8 bits in a byte, so 100 Mbps = 12.5 MB/s maximum. Actual speeds may be lower due to network overhead, server limits, or congestion.
MB (uppercase B) means megabytes, while Mb (lowercase b) means megabits. The difference is a factor of 8. File sizes use bytes (MB, GB), while network speeds typically use bits (Mbps, Gbps).
For HD streaming (1080p), you need about 5-10 Mbps. For 4K streaming, you need 25-50 Mbps. For gaming and video calls, 10-25 Mbps is usually sufficient. Multiple users will need more bandwidth.
Yes! 1 Gbps (gigabit per second) equals 1000 Mbps (megabits per second). This is also equal to 125 MB/s (megabytes per second) for actual file downloads.
