Gb To Minutes Calculator

The Gb To Minutes Calculator helps you find out how long a file will last when streamed or transferred based on its size in gigabytes and the bitrate of the content. It is especially useful for people who are working with video or audio files and want to estimate the playback or download duration. This calculator is most commonly used in the digital media, telecommunications, and data storage industries. It can help content creators, editors, and users understand how much time it will take to watch or download a certain amount of data.

This tool falls under the Data Conversion Calculators category.

formula

General Formula:
Minutes = (GB × 1024 × 1024 × 1024 × 8) / (Bitrate × 60)

Simplified Formula:
Minutes = (GB × 8589934592) / (Bitrate × 60)

Where:
GB = File size in gigabytes
Bitrate = Bitrate of the content in bits per second (bps)
(e.g., 5 Mbps = 5,000,000 bps)
60 = Seconds per minute
8589934592 = Number of bits in 1 GB (1 GB = 1024³ bytes × 8)

Optional Unit Conversion for Bitrate:
If bitrate is in:
Kbps: multiply by 1,000
Mbps: multiply by 1,000,000
Gbps: multiply by 1,000,000,000

It is important to make sure the bitrate is in bits per second before using it in the formula.

Commonly Used Data and Bitrate Conversion Table

All values are approximate. This table helps quickly estimate durations without manual calculation.

Example

Let’s say you have a video file that is 2 GB in size and it is encoded at a bitrate of 8 Mbps.

Step 1: Convert Mbps to bps
8 Mbps = 8 × 1,000,000 = 8,000,000 bps

Step 2: Use the formula
Minutes = (2 × 8589934592) / (8000000 × 60)
Minutes = 17179869184 / 480000000
Minutes ≈ 35.79

So, a 2 GB file at 8 Mbps will last approximately 35.79 minutes.
