Why Convert Terabytes to Gigabytes?
Converting between terabytes (TB) and gigabytes (GB) is one of the most common digital storage conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert TB to GB saves time and prevents errors.
Digital storage conversions (TB to GB) are essential for IT professionals, content creators, and everyday computer users. Understanding the difference between bits and bytes is crucial when calculating internet speeds versus file sizes. Photographers and video editors need to convert terabytes and gigabytes to manage backups and estimate cloud storage costs. Confusion often arises between binary (1024) and decimal (1000) prefixes used by hardware manufacturers versus operating systems, leading to apparent 'missing' space on hard drives. Accurate conversion helps in planning server capacity, data transfer times, and device purchases.
How to Convert Terabytes to Gigabytes
To convert terabytes to gigabytes, use the following formula:
GB = TB × 1000
Example: 1 TB = 1000 GB
For example, 5 TB = 5000 GB, 10 TB = 10000 GB, and 100 TB = 100000 GB. For larger values, 1000 TB = 1000000 GB. Conversely, 1 GB = 0.001 TB. Our calculator above performs this conversion instantly with full precision — no rounding errors.
Common Mistakes to Avoid
- Bit vs Byte: 1 Byte = 8 Bits. Internet speed is usually bits (Mb/s), file size is Bytes (MB).
- Base 10 vs Base 2: Hard drive makers use Base 10 (1KB=1000B), OS uses Base 2 (1KiB=1024B).
- B vs b: MB is Megabyte, Mb is Megabit.
Pro Tips
- Storage buying: A 1TB drive usually shows as ~930GB in Windows due to decimal/binary difference.
- Data caps: Streaming HD video uses ~3GB/hour.
- Backup rule: 3-2-1 rule: 3 copies, 2 media types, 1 offsite.
