What do my speed test results mean?


The basics
  1. 8 Kilobits (Kb) = 1 Kilobyte (KB)
    8 Megabits (Mb) = 1 Megabyte (MB)

    KB and MB are measurements of data file sizes and storage.
  2. Kbps and Mbps are short for "Kilobits per second" and "Megabits per second" and are measurements of data transfer rates (also known as connection speed).
  3. To estimate how long it would take to download a large file based upon your connection speed, you can use the following simple mathematical equation:(Convert file size to Mb) / coneection speed (in Mbps) = # of seconds to complete download.
    So if your connection speed is 16 Mbps then, then you could theoretically download a 2 MB file, such as a high-resolution digital photo, in approximately one second.
    (2 MB x 8 Mb) / 16 Mbps = 1 second

How long does it take to download a file at different connection speeds?

Instructions: Our calculator measures the estimated time needed to download a file at different connection speeds. Simply type in the file size in the field below and choose a measurement unit. The fields below will automatically populate with estimated download times *based on connection speed.
MB (Megabytes)
GB (Gigabytes)
TB (Terabytes)
33.6 K (Modem)33,600 bps41 mins, 36 secs
56 K (Modem)56,000 bps24 mins, 57 secs
64 K (DS-0)64,000 bps21 mins, 50 secs
128 K (ISDN)128,000 bps10 mins, 55 secs

640 K (DSL/Cable)640,000 bps2 mins, 11 secs
768 K (DSL/Cable)768,000 bps1 min, 49 secs
T1, DS-11.544 Mbps54 secs
T3, DS-344.736 Mbps1 sec
OC-151.840 Mbps1 sec
OC-3155.520 MbpsLess than a second.
OC-12622.520 MbpsLess than a second.
OC-482.488 GbpsLess than a second.

*Note: these calculations assume a "perfect" connection at the stated speed. Actual performance will vary due to retries, latency, transmission protocol requirements, and other concurrent traffic.
