How to Convert Gigabits per second to Megabytes per second (Gbps to MB/s)

Updated 5 Oct 2026 in Unit Converters

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 megabytes per second by hand, with examples and a quick-reference table.

The conversion

To convert gigabits per second to megabytes per second, multiply the value by 125. To go the other way, divide by the same number (or multiply by 0.008). For a quick estimate, multiply by about 120.

Megabytes per second = gigabits per second × 125

Mistakes to avoid

Multiplying when you should divide

Converting to a smaller unit gives a bigger number, and converting to a larger unit gives a smaller one. If your answer moves the wrong way, you have inverted the factor.

Dropping the units

A bare number without a unit is easy to misread later. Always write the unit with the result.

Mixing similar-sounding units

US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.

Background

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.

Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.

For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
