Bits to Gigabytes Converter

Summary

This converter takes any bit count and outputs the equivalent in gigabytes under both common standards. The SI decimal gigabyte (GB) equals exactly 1,000,000,000 bytes — the value used on storage product packaging. The IEC binary gibibyte (GiB) equals 1,073,741,824 bytes (2^30) — the value operating systems use internally when reporting disk or RAM size. The gap between the two is about 7.4%, which explains why a "1 TB" hard drive shows as roughly 931 GiB in Windows.

How it works

1. Enter any number of bits in the input field.
2. Optionally change the "Convert from" unit if your value is already in kilobits, megabits, or gigabits.
3. Click Convert (or press Enter) to calculate.
4. The converter divides by 8 to get bytes, then divides by 10^9 for GB (SI) and 2^30 for GiB (binary).
5. Copy any result with the copy icon next to it.

Use cases

• Check how many gigabytes a large file or dataset occupies when given only a bit count.
• Convert network throughput from gigabits per second to gigabytes per second.
• Translate storage specs between marketing labels (SI) and OS reports (binary).
• Calculate Blu-ray or 4K video file sizes from raw bitrate data.
• Understand RAM capacity differences between manufacturer specs and OS readings.
• Convert satellite or cellular data caps expressed in bits to practical GB values.
