Mbps to Gbps converter
1000 Mbps is exactly 1 Gbps, and a 100 Mbps plan is 0.1 Gbps. Enter a speed in megabits per second and get the gigabit figure used on switchports, fibre hand-offs and cloud network agreements, with no 1024 shortcut. Free in your browser.

An Mbps-to-Gbps converter turns a network or link speed quoted in megabits per second into the gigabits-per-second figure used on backbone ports, data-center fabrics, and multi-gig marketing pages. Rough mental shortcuts that swap mega for giga without the thousand factor—or confuse bit rates with byte rates—are rejected in favour of pure rate conversion, so homework checks and network documentation match the same deterministic contract.
Why megabits per second become gigabits by dividing by one thousand
Megabits per second and gigabits per second measure the same underlying bit rate, but the giga prefix sits three decimal orders of magnitude above mega under SI. Consumer plans often quote one hundred or five hundred Mbps while switchports, fibre hand-offs, and cloud network SLAs speak in Gbps; students, support agents, and automation scripts need a reliable bridge that never confuses a megabit-per-second rate with a megabit quantity, a megabyte-per-second throughput, or a binary one-thousand-twenty-four factor.
Teachers can contrast the exact path with a rough order-of-magnitude guess so learners see how a missing divide-by-thousand error inflates capacity estimates by three orders of magnitude on large links.
Practical tips, checks, and related searches
Round-trip sanity checks are easy: convert one thousand Mbps and confirm you receive exactly one Gbps after rounding, or convert one hundred Mbps and confirm zero point one Gbps. If your source quotes a file size in megabits rather than a rate in megabits per second, do not feed that quantity into this tool unchanged—use a megabits-to-megabytes or general data-size converter for storage quantities, and use a multi-unit data-rate converter when you need Mbps versus MB per second or mixed families in one call.
Stay inside the absolute range so the quotient cannot overflow into a non-finite result the solver must reject. When teaching unit analysis, pair a simple ISP-plan example with the pure rate conversion so students see that the same divide-by-thousand constant appears in both consumer marketing and data-center port math. This landing targets people searching for Mbps to Gbps, convert megabits per second to gigabits, or a divide-by-one-thousand rate calculator; it is not a multi-unit data-rate hub, not a Gbps-to-Mbps primary form, not a transfer-time estimator, and not a binary-prefix converter.
Prefer this capability when the input is already in Mbps and you only need Gbps; if you must convert among many rate units in one call, use a broader data transfer rate converter instead.
What you can do with it
ISP plan and port speed explanations
Convert megabit-per-second figures from carrier documentation into gigabits per second so customers can compare plan speeds with multi-gig switchports and fibre hand-offs.
FAQ
How do I convert Mbps to Gbps?
Send a finite non-negative number in megabits per second. Example: 1000 Mbps → 1 Gbps.
Is the factor 1000 or 1024?
This tool uses 1000 (SI decimal). Network link speeds and ISP marketing use decimal SI prefixes for bit rates, not binary 1024 factors.
What happens if mbps is negative or missing?
Negative data rates and missing or non-numeric fields are rejected and are not billed.
How many Gbps is 100 Mbps?
It is 0.1 Gbps. Divide by 1000: 100 Mbps is one tenth of a gigabit per second, and 1000 Mbps make exactly 1 Gbps.
Can I use it for a file size in megabits?
No. It converts speeds per second, not amounts of data. For a size in megabits use a megabits-to-megabytes converter, and for megabytes per second use a data-rate converter.

For developers — API access
Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.
API endpoint
Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

Technical notes
Invalid or missing input fails with a clear invalid_input error instead of inventing a number.
Why megabits per second become gigabits by dividing by one thousand
In telecommunications and networking, bit-rate marketing and IEEE link speeds use decimal SI factors, not binary kibibit or mebibit powers of two: one kilobit per second is one thousand bits per second, one megabit per second is one million bits per second, and one gigabit per second is one billion bits per second. That makes the conversion a single exact division: gigabits per second equals megabits per second divided by one thousand, or equivalently megabits per second times zero point zero zero one.
How to call the API and what comes back
Absolute values must stay within the published limit of one trillion. Prefer bare numbers when you control the client; string numbers are accepted only when they match a strict finite numeric pattern without unit suffixes or thousand separators. Send a JSON body with one required finite non-negative number field named mbps. Aliases megabits_per_second, Mbps, value, amount, rate, and speed are accepted so SDK clients and form posts can use the name that fits the product. On success the response echoes rounded mbps, sets gbps, result, and converted to the same rounded gigabit-per-second magnitude, unit to the token Gbps, from_unit to Mbps and to_unit to Gbps, factor to zero point zero zero one, mbps_per_gbps to one thousand, formula to the string gbps equals mbps divided by one thousand, message to a short English summary, and steps to an ordered array of substitution lines. Failed validation—missing fields, non-finite numbers, bare plus or minus signs, non-numeric strings, negative rates, values outside absolute limits, or a non-finite converted result—returns invalid_input and is never charged. Pricing is a flat $0.002 per successful request with unit item.
Practical tips, checks, and related searches
Failed tasks that return invalid_input do not consume prepaid balance, which keeps exploratory scripts cheap when learners deliberately omit mbps or pass text.
Integration use cases
Homework and networking labs
Students convert classroom Mbps readings to Gbps and compare hand work against deterministic steps before submitting worksheets or coding fixtures.
Automation and capacity macros
Scripts and ops tools normalize Mbps totals from tickets and dashboards into Gbps for SI datasheets, CRM notes, and API payloads without fragile hand-typed factors.
Technical questions
What is the exact conversion factor?
Divide by 1000 (or multiply by 0.001). The factor is exact from the SI definition 1 Gbps = 1000 Mbps used in networking bit rates.
What does the Mbps to Gbps converter cost?
The browser tool is free. API requests use prepaid KIT balance at $0.002 per successful call; invalid input is not billed.
