How Many Bytes in a Terabyte?
Quick Answer
There are approximately 1.1 trillion bytes in a terabyte (binary) or exactly 1 trillion (decimal).
1 TiB = 2⁴⁰ ≈ 1.1 trillion bytes
Understanding the Conversion
One binary terabyte (TiB) = 2⁴⁰ = 1,099,511,627,776 bytes (≈1.1 trillion). The decimal TB = 10¹² = 1,000,000,000,000 bytes. A 1 TB hard drive holds about 931 GiB as reported by Windows, due to binary vs. decimal conversion.
Formula
1 TiB = 2⁴⁰ ≈ 1.1 trillion bytes
Common Examples
| Description | Value |
|---|---|
| A 1 TB hard drive | ≈931 GiB of usable space (OS view) |
| Photos on 1 TB | ≈200,000–500,000 photos |
| Video on 1 TB (1080p) | ≈500 hours |
