terabytes = gigabytes × 0.001. So 18,000 gigabytes is back to 18 terabytes; one gigabyte is 0.001 terabytes. See the gigabytes to terabytes table.

Quick estimate in your head

For a rough answer, multiply by about 1000: 18 × 1000 ≈ 18,000 gb, against the exact 18,000 gb (0.0% out). Good enough to check that a calculated result is sensible.

Common mistakes

The usual slip is using the factor the wrong way round. A terabyte is bigger than a gigabyte, so the number of gigabytes must come out larger than the number of terabytes. If your answer goes the other way, divide instead of multiplying.
