Internet Speed Converter
Know your file's download time and your data plan's real cost per gigabyte before you commit.
Why does the advertised speed differ from what you actually see?
Internet providers advertise speed in megabits per second (Mbps), but your download manager or browser reports speed in megabytes per second (MB/s) — eight times smaller, since there are 8 bits in a byte. This tool does that conversion for you and estimates the real download time.
The real cost per gigabyte
When you're choosing a data plan, knowing the exact cost per gigabyte makes it much easier to compare options — the bigger plan isn't always the better deal. Enter a plan's price and data allowance to see its true per-GB cost, and optionally estimate the cost of a specific amount of usage.
Frequently asked questions
Why do Mbps and MB/s get confused so often?
Because they both start with “M,” but Mbps measures your connection's raw speed while MB/s is how download managers and browsers usually display progress. To convert, divide the Mbps figure by 8.
Why is my real download speed lower than the calculated number?
Network traffic, the source server's limits, geographic distance, and bandwidth shared across multiple devices can all reduce real-world speed; this tool only shows the theoretical ceiling.
How does cost-per-GB help me?
By calculating the cost per gigabyte for several plans, you can pick the cheapest option that actually matches how much data you use.
Does this work for mobile data too?
Yes — the speed-conversion and cost-per-GB formulas are identical for home broadband (cable/fiber) and mobile data plans.
