How to Convert Kilobytes to Gigabytes (KB to GB)
Data conversions explain why a 1 TB drive shows less space on your computer and help compare mobile plans sold in gigabytes. This guide shows how to convert kilobytes into gigabytes by hand, with examples and a quick-reference table.
The conversion
To convert kilobytes to gigabytes, multiply the value by 1.000000e-06. To go the other way, divide by the same number (or multiply by 1,000,000). Because the factor is tiny, scientific notation keeps the numbers manageable.
Gigabytes = kilobytes × 1.000000e-06
Worked examples
- 3 KB = 3.000000e-6 GB
- 12.5 KB = 1.250000e-5 GB
- 75 KB = 7.500000e-5 GB

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

Mistakes to avoid
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.
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.
Background
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.
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.
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.
