# GiB to GB Convert gibibytes to gigabytes with decimal vs binary interpretation, alternate-system comparison, and network-speed-aware transfer estimates > Canonical page: https://elysiatools.com/en/tools/gib-to-gb - **Category:** Math & Numbers - **Keywords:** data storage, unit conversion, file size, GiB, GB ## Overview Convert binary gibibytes (GiB) to decimal gigabytes (GB) with precision. This tool calculates the exact storage differences between operating systems that use binary measurements and hardware manufacturers that use decimal units, while also estimating network transfer times based on your connection speed. ## Inputs - **Value** (text): e.g. 465 - **Unit System** (select) - **Transfer Speed (Mbps, optional)** (number) - **Decimal Precision** (number) ## When to use - When provisioning cloud storage volumes where providers bill in decimal GB but virtual machines report space in binary GiB. - When reconciling differences between physical hard drive capacities and the storage capacity reported by your operating system. - When planning data migrations and estimating how long a specific GiB payload will take to transfer over a network connection. ## How it works - Enter the data volume value in gibibytes (GiB) that you want to convert. - Select the target unit system interpretation (Decimal SI or Binary-Compatible) and set your desired decimal precision. - Optionally input your network transfer speed in Mbps to calculate estimated download or upload times. - Submit the values to generate a detailed JSON summary containing the converted GB value, alternative system comparisons, and transfer duration. ## Use cases - Cloud infrastructure provisioning to match virtual machine disk allocations with physical storage limits. - Data center migration planning to estimate transfer windows for large database backups over dedicated network links. - Hardware purchasing validation to reconcile operating system storage reports with vendor-specified drive capacities. ## Frequently asked questions ### What is the difference between GiB and GB? GiB (gibibyte) is a binary unit based on powers of 2 (1 GiB = 1,073,741,824 bytes), whereas GB (gigabyte) is a decimal unit based on powers of 10 (1 GB = 1,000,000,000 bytes). ### Why does my operating system show less storage space than the drive packaging? Operating systems like Windows often measure storage in binary GiB but label it as 'GB', whereas manufacturers sell drives in decimal GB. ### How does the transfer speed option work? By entering your network bandwidth in Mbps, the tool calculates the theoretical time required to move the specified GiB payload over that connection. ### What is the conversion factor from GiB to GB? 1 GiB is equal to approximately 1.07374 GB under the standard decimal SI system. ### Can I adjust the decimal precision of the output? Yes, you can specify the decimal precision from 0 to 10 decimal places using the precision configuration option. ## Related tools - [Acre to Hectare](https://elysiatools.com/en/tools/acre-to-hectare): Convert acres to hectares with configurable decimal precision - [Acre to Square Feet](https://elysiatools.com/en/tools/acre-to-square-feet): Convert acres to square feet with configurable decimal precision - [Acre to Square Meter](https://elysiatools.com/en/tools/acre-to-square-meter): Convert acres to square meters with configurable decimal precision - [Arcminutes to Degrees](https://elysiatools.com/en/tools/arcminutes-to-degrees): Convert arcminutes to degrees with configurable decimal precision - [Arcseconds to Degrees](https://elysiatools.com/en/tools/arcseconds-to-degrees): Convert arcseconds to degrees with configurable decimal precision - [ATM to KPa](https://elysiatools.com/en/tools/atm-to-kpa): Convert standard atmospheres to kilopascals with configurable decimal precision - [Bar to KPa](https://elysiatools.com/en/tools/bar-to-kpa): Convert bar to kilopascals with configurable decimal precision - [Bar to PSI](https://elysiatools.com/en/tools/bar-to-psi): Convert bar to pounds per square inch with configurable decimal precision ## Samples - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Android Image Processing Java Samples](https://elysiatools.com/en/samples/android-image-processing-java): Android Java image processing examples including reading/saving images, scaling, and format conversion - [Android Image Processing Kotlin Samples](https://elysiatools.com/en/samples/android-image-processing-kotlin): Android Kotlin image processing examples including reading/saving images, scaling, and format conversion - [Web Image Processing Rust Samples](https://elysiatools.com/en/samples/web-image-processing-rust): Web Rust image processing examples including image read/save, scaling, and format conversion ## Related content - [Data Size Unit Conversion Without the KB and KiB Confusion](https://elysiatools.com/en/hubs/data-size-unit-conversion): Convert between bits, bytes, and the decimal SI prefixes KB, MB, GB, TB plus the binary IEC prefixes KiB, MiB, GiB, TiB with the system of every number pinned down before you calculate.
