Mbps to Gbps Calculator — Network Speed Converter
Enter any speed in megabits per second (Mbps) and instantly get Gbps, MB/s, GB/s, Kbps, Tbps and bytes-per-second equivalents — with the key conversions explained step by step.
Mbps
Decimal: 1 Gbps = 1 000 Mbps
Gbps — divide by 1 000 (1 Gbps = 1 000 Mbps)
MB/s — divide by 8 (8 bits = 1 byte)
GB/s — divide by 8 000
- 1
Kilobits per second
1,000 × 1,000 = 1,000,000 - 2
Megabytes per second
1,000 ÷ 8 = 1251 byte = 8 bits - 3
Gigabits per second
1,000 ÷ 1,000 = 11 Gbps = 1 000 Mbps (decimal SI)
How does this calculator work?
Divide Mbps by 1 000 to get Gbps (network speeds use decimal SI: 1 Gbps = 1 000 Mbps). Divide by 8 to get MB/s (since 8 bits = 1 byte). So 1 000 Mbps = 1 Gbps = 125 MB/s. All network speed units are decimal — never binary/IEC.
Formula
How this is calculated
Network speeds are always measured in bits per second, not bytes. The decimal (SI) prefix hierarchy applies: 1 Kbps = 1 000 bps, 1 Mbps = 1 000 Kbps, 1 Gbps = 1 000 Mbps, 1 Tbps = 1 000 Gbps. So converting Mbps to Gbps is simply division by 1 000 — a 1 000 Mbps link is exactly 1 Gbps.
File sizes and download speeds displayed in operating systems and browsers are measured in bytes. Because 1 byte = 8 bits, you divide the bit rate by 8 to get the byte rate: 100 Mbps = 12.5 MB/s. This is the single most common source of confusion when comparing advertised "Mbps" broadband speeds with the "MB/s" shown in a download manager.
All network speed units (Mbps, Gbps) use decimal (SI) powers of 1 000 — not binary IEC powers of 1 024. This differs from how OS file sizes are often reported (MiB, GiB). There is no binary equivalent of Mbps in standard usage; all ISP and hardware speed ratings are decimal.
Frequently asked questions
1 Gbps = 1 000 Mbps exactly (decimal SI). Gigabit Ethernet, fibre optics, and 5G speeds are rated in Gbps. A typical home broadband of 500 Mbps is 0.5 Gbps; a 10 Gbps data-centre link = 10 000 Mbps.
Because 1 byte = 8 bits. Your download manager measures in megabytes per second (MB/s), while your ISP advertises in megabits per second (Mbps). 100 Mbps ÷ 8 = 12.5 MB/s — both represent identical throughput.
Gigabit fibre broadband (1 Gbps down) is common for high-end residential users. Data-centre interconnects run at 10, 25, 40, 100 or 400 Gbps. 5G sub-6 GHz peaks at 1–3 Gbps; mmWave 5G can exceed 4 Gbps. Wi-Fi 6E and Wi-Fi 7 reach up to 9.6 Gbps in ideal conditions.
