## Overview

Convert raw byte values into gigabytes (GB) using either decimal (SI, 1000-based) or binary (1024-based) unit systems. This tool also calculates network transfer times based on custom connection speeds and provides side-by-side comparisons to help you understand storage capacities accurately.

## Inputs

- **Value** (text): e.g. 1073741824
- **Unit System** (select)
- **Transfer Speed (Mbps, optional)** (number)
- **Decimal Precision** (number)

## When to use

- When analyzing server log files or database sizes that are output in raw bytes and need to be presented in gigabytes.
- When comparing storage drive capacities where manufacturers use decimal gigabytes but operating systems report binary gigabytes.
- When estimating how long it will take to upload or download a specific byte-sized payload over a given network bandwidth.

## How it works

- Enter the raw byte value you want to convert in the input field.
- Select your preferred unit system (Decimal 1000-based or Binary 1024-based) and set the desired decimal precision.
- Optionally enter a network transfer speed in Mbps to calculate the estimated transmission time.
- Submit the form to generate a detailed JSON summary comparing both unit systems and displaying the transfer estimate.

## Use cases

- Cloud storage billing verification by converting raw byte usage metrics from API responses into billable gigabytes.
- Network bandwidth planning to estimate download times for large software assets or database backups.
- System administration tasks where disk space usage reported in bytes needs to be formatted for human-readable reports.

## Frequently asked questions

### What is the difference between decimal and binary GB conversion?

Decimal conversion uses 1,000,000,000 bytes per gigabyte, while binary conversion uses 1,073,741,824 bytes per gigabyte.

### Can I calculate how long it takes to transfer the converted data?

Yes, by entering your network speed in Mbps, the tool estimates the transfer time for the specified byte volume.

### What is the default decimal precision of the output?

The default precision is 4 decimal places, but you can adjust it between 0 and 10.

### Why does my operating system show less space than the hard drive packaging?

Hard drive manufacturers use decimal GB (1000-based), whereas operating systems often calculate storage using binary GB (1024-based).

### Does this tool support converting other units like MB or TB?

This specific tool converts raw bytes directly to gigabytes, providing comparisons for both standard systems.
