How to Convert Gigabits per second to Megabits per second (Gbps to Mbps)
Broadband plans in Singapore are sold in Mbps and Gbps, while download managers show MB/s, so converting between them shows how fast files really arrive. This guide shows how to convert gigabits per second into megabits per second by hand, with examples and a quick-reference table.
The conversion
To convert gigabits per second to megabits per second, multiply the value by 1,000. To go the other way, divide by the same number (or multiply by 0.001). For a quick estimate, multiply by about 1,000.
Megabits per second = gigabits per second × 1,000
Worked examples
- 3 Gbps = 3,000 Mbps
- 12.5 Gbps = 12,500 Mbps
- 75 Gbps = 75,000 Mbps

Common questions
Is Gbps to Mbps exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.

Mistakes to avoid
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Background
Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
Singapore adopted the metric system in the 1970s, replacing imperial units and traditional Chinese measures in most official uses. Metric units are now standard in schools, trade and government, but older units survive in property, markets and imported goods.
