About These Units
Digital data sizes scale by factors of 1024 (binary) or 1000 (decimal). The IEC officially distinguishes KiB (kibibyte, 1024 bytes) from KB (kilobyte, 1000 bytes), but most software still uses KB to mean 1024 bytes. This tool follows the common binary convention (1 KB = 1024 B). Knowing data size conversions is critical for storage planning, network bandwidth budgeting, cloud cost estimation, and avoiding 'disk full' surprises.
About Terabytes
The terabyte (TB) is 1,024 GB (binary) or 1,000 GB (decimal) — modern hard drive scale.
Coined in the 1960s; entered consumer use in the late 2000s when 1 TB hard drives became affordable.
Used for hard drives, NAS storage, cloud backup plans, and small-business data totals.
About Gigabytes
The gigabyte (GB) is about 1 billion bytes — the modern standard for RAM, storage, and mobile data plans.
Became commonplace in the 2000s with consumer hard drives reaching multi-GB capacities.
Used for movie files, mobile data caps (e.g., 5 GB/month), USB drives, and SSD specifications.
When Conversion Is Needed
Terabytes and Gigabytes belong to different measurement systems, so conversion becomes necessary when comparing values across the two units, or when forwarding a document or specification written in one unit to someone who uses the other. The quick-reference table on this page shows how common values in Terabytes translate to Gigabytes, so memorizing or bookmarking the most frequently-used values is often a worthwhile shortcut.
Real-World Use Cases
Storage Planning
When sizing cloud buckets, NAS drives, or backup media, converting between GB and TB clarifies cost vs capacity. 1 TB = 1024 GB in this tool's convention — enough for roughly 250,000 photos at 4 MB each.
Bandwidth & Downloads
Network speeds are quoted in megabits per second (Mbps), but file sizes in megabytes (MB). 100 Mbps = 12.5 MB/s, so a 1 GB game download takes about 80 seconds on a fast connection.

Frequently Asked Questions
Is 1 KB equal to 1000 or 1024 bytes?
Hard drives and ISPs use 1000-based (decimal) — that's why your '1 TB' drive shows ~931 GB in your OS. RAM and OS reports use 1024-based (binary). This tool uses 1024-based to match what most users see in their OS.
What comes after a Petabyte?
After PB: Exabyte (EB), Zettabyte (ZB), Yottabyte (YB). Each is 1024x the previous. As of the 2020s, global internet traffic is measured in zettabytes per year.
How many photos fit in 1 GB?
Roughly 250–500 high-quality JPEGs (3–5 MB each from a modern phone), or 200 RAW files (5 MB each), or about 300 short 4K videos (1 minute each at ~3 MB). Exact numbers depend on quality settings.
