How the conversion works
Decimal networking (most common)
1 Mbps = 1000 kbps
Mbps = kbps ÷ 1000
kbps = Mbps × 1000
Binary style
1 Mbps = 1024 kbps
Mbps = kbps ÷ 1024
kbps = Mbps × 1024
Why is there a 1000 vs 1024 confusion?
Networking vendors, ISPs and speed tests typically use decimal powers of 10: 1,000, 1,000,000, etc. Some software and storage contexts rely on binary powers of 2: 1,024, 1,048,576, etc. Our toggle mimics both.
FAQ
1. Is 1000 kbps the same as 1 Mbps?
Yes in decimal networking. In binary it’s about 0.977 Mbps — close, but not exact.
2. Can I convert to MB/s (megabytes per second)?
First convert kbps → Mbps here, then divide by 8 to get MB/s, because 8 bits = 1 byte.
3. My ISP says 50 Mbps but I see ~6.25 MB/s. Why?
Because 50 megabits per second ÷ 8 = 6.25 megabytes per second. Bits vs bytes.
