# File size = 61.49 MB # 1 MB = 1024 KB # Bitrate = 128 kbps (kilobits per second) # Calculation: # Size in Kilobits = 61.49 * 1024 * 8 # Duration in seconds = Size in Kilobits / 128 file_size_mb = 61.49 bitrate_kbps = 128 size_bits = file_size_mb * 1024 * 1024 * 8 duration_seconds = size_bits / (bitrate_kbps * 1000) # Also check for standard 1MB = 1,000,000 bytes definition which is common in bitrate math duration_seconds_std = (file_size_mb * 1000 * 1000 * 8) / (bitrate_kbps * 1000) print(f"{duration_seconds=}") print(f"{duration_seconds_std=}") Use code with caution.
