Formula and method
This calculator computes Estimated size, Estimated size directly in your browser without sending data to an external server.
Mathematical formula
- Estimated size:
bitrate × minutes × 60 ÷ 8 ÷ 1024 - Estimated size:
bitrate × minutes × 60 ÷ 8
Variables and parameters
- Bitrate (bitrate): default value 12 Mbps.
- Duration (minutes): default value 30 minutes.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
Examples
- Example: with Bitrate = 12 Mbps, Duration = 30 minutes, this calculator returns Estimated size = 2.64 GB, Estimated size = 2700 MB.
