💡 Bits vs Bytes
Internet speeds are measured in bits (Mbps), while file sizes use bytes (MB). There are 8 bits in 1 byte, so 100 Mbps = 12.5 MB/s.
📊 Real vs Advertised Speed
ISPs advertise in 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.
