Steam download speed: MB/s vs your plan's Mbps
Steam shows download speed in megabytes per second (MB/s), while internet plans are sold in megabits per second (Mbps), so multiply Steam's number by 8 before comparing: 40 MB/s is 320 Mbps. A 500 Mbps plan tops out at 62.5 MB/s in Steam, and a steady 55–60 MB/s means it is running at full speed.
Plan speeds in Mbps and MB/s
| Plan | Maximum MB/s | Typical MB/s (≈90%) | 1 GB takes | 50 GB takes |
|---|---|---|---|---|
| 25 Mbps | 3.125 MB/s | 2.8 MB/s | 5 minutes, 56 seconds | 4 hours, 56 minutes, 18 seconds |
| 50 Mbps | 6.25 MB/s | 5.6 MB/s | 2 minutes, 58 seconds | 2 hours, 28 minutes, 9 seconds |
| 100 Mbps | 12.5 MB/s | 11.3 MB/s | 1 minute, 29 seconds | 1 hour, 14 minutes, 4 seconds |
| 200 Mbps | 25 MB/s | 22.5 MB/s | 44 seconds | 37 minutes, 2 seconds |
| 300 Mbps | 37.5 MB/s | 33.8 MB/s | 30 seconds | 24 minutes, 41 seconds |
| 500 Mbps | 62.5 MB/s | 56.3 MB/s | 18 seconds | 14 minutes, 49 seconds |
| 1 Gbps | 125 MB/s | 112.5 MB/s | 9 seconds | 7 minutes, 24 seconds |
| 2 Gbps | 250 MB/s | 225 MB/s | 4 seconds | 3 minutes, 42 seconds |
Typical assumes about 90% of the plan speed arrives as file data (protocol overhead and real-world losses). The server, Wi-Fi and disk also have to keep up.
The ×8 rule with real Steam readings
A byte is 8 bits, so the same download looks eight times smaller in MB/s. The plan table above lists the most each tier can show in Steam and a typical figure at about 90%. To judge your own reading, turn it into a share of the plan:
share of plan = Steam MB/s × 8 ÷ plan Mbps
- 11 MB/s on 100 Mbps: 88 Mbps, 88%. Full speed.
- 30 MB/s on 300 Mbps: 240 Mbps, 80%. Fine, with a little lost somewhere.
- 60 MB/s on 500 Mbps: 480 Mbps, 96%. As good as it gets.
- 45 MB/s on 1 Gbps: 360 Mbps, 36%. Something other than the plan is the limit; see below.
Roughly 85% or more on a wired PC is a healthy download. The Mbps to MB/s converter does the arithmetic in both directions.
Why Steam uses MB/s, and how to switch to bits
Steam is writing files to your drive, and file sizes are counted in bytes, so bytes per second tells you directly how long a game of a given size will take. Providers and speed tests count bits because that is how networks have always measured line speed. Neither is wrong; they are different units for the same flow, which Mbps vs MB/s explains in full.
Steam Support says the same: internet speeds are measured in bits per second, Steam downloads in bytes per second, and you can either multiply Steam's figure by 8 or switch the client to display download information in bits. Its own example: 768 KB/s is 6,144 kb/s, about 6 Mbps. With bits displayed, a reading of 480 Mbps can be set straight against a 500 Mbps plan. Watch the letter case either way: MB/s is megabytes and Mb/s or Mbps is megabits. What is MB/s? covers byte-based units, including MiB/s.
Why Steam may be slower than your plan
- Content servers and download region. Steam picks a content server by your location. If downloads are slower than expected, Steam Support suggests checking Steam > Settings > Downloads > Download region, choosing the region you are in or the closest one, and trying other nearby regions.
- A bandwidth limit. The same Downloads tab has a download speed limit. Steam notes that these limits are shown in kilobytes and megabytes per second (or bits, if you switched the display), so a limit meant as 50 Mbps but set as 50 MB/s is eight times off, and vice versa.
- Security or filtering software. According to Steam Support, some third-party programs, including internet security and packet-filtering software, can make Steam use the wrong content servers.
- The wrong "speed" to compare against. The connection speed shown in your system tray or network settings is your link to the local network (Wi-Fi or Ethernet), not your internet speed. Compare Steam with your plan or a speed test instead.
- Wi-Fi and other traffic. Run the same comparison on a cable, and pause other large downloads, cloud backups and streams, to rule these out.
How long a Steam download takes
With the MB/s figure Steam shows, you don't need to convert at all: size in GB × 1,000 ÷ MB/s = seconds. An 80 GB game at 35 MB/s takes 80,000 ÷ 35 ≈ 2,286 s, about 38 minutes, before installation. From a plan speed instead, a 100 GB game takes 44 min 27 s at 300 Mbps and 13 min 20 s at 1 Gbps at full speed; how long to download 100 GB has every common tier, and the download time calculator handles any size.
A quick checklist when Steam is slow
- Convert the reading: Steam MB/s × 8 = Mbps. If it is 85% of your plan or more, nothing is wrong.
- Run a speed test on the same PC, preferably on a cable, and compare it with your plan in the speed test checker. If the test is also low, the problem is the line or Wi-Fi, not Steam.
- If the speed test is fine but Steam is slow, try another download region and check any security software that filters network traffic.
- Pause other downloads and backups, and check for a Steam bandwidth limit.
- If Steam shows the rate in another unit, such as kB/s on a slow line, the bytes to Mbps converter handles all of them.
Key takeaways
- Steam shows MB/s (bytes); plans are sold in Mbps (bits). Multiply Steam's figure by 8.
- 100 Mbps shows as up to 12.5 MB/s, 500 Mbps up to 62.5 MB/s, 1 Gbps up to 125 MB/s.
- 85% of your plan or more in Steam on a wired PC is a healthy download.
- If a speed test is fine but Steam is slow, check the download region, a Steam bandwidth limit, security software and Wi-Fi.
- Download time in seconds = GB × 1,000 ÷ Steam's MB/s.
Frequently asked questions
Is Steam download speed in MB/s or Mbps?
By default Steam shows megabytes per second (MB/s). Multiply by 8 to get megabits per second, the unit of your plan: 25 MB/s is 200 Mbps.
What Steam download speed should I get on a 100 Mbps plan?
At most 12.5 MB/s. A steady 11–12 MB/s means the plan is running at full speed.
What Steam download speed should I get on gigabit?
At most 125 MB/s. A wired gigabit connection typically tests around 940 Mbps, about 117.5 MB/s, so 100–117 MB/s in Steam is a good result if Steam's content server keeps up.
Why is Steam slower than my speed test?
A speed test measures the line to a nearby test server. Steam also depends on its content servers, your download region and any bandwidth limit set in Steam, and security software can make it use the wrong servers. If the speed test is fine, try a different download region first.
Can I make Steam show Mbps?
Yes. Steam Support describes switching the client to display download information in bits per second, which you can compare directly with your plan. Otherwise multiply the MB/s figure by 8.
