Pro Tips for Accurate Conversions

Quick estimate: divide by 1000

For rough planning, 1000 GB ≈ 1 TB (actually 0.977 TB binary, close enough for estimates).

Annual data growth

Average users add 100-500 GB/year. Plan for 1-2 TB to last several years.

Cloud vs local

1 TB cloud storage typically costs $10-12/month. Consider costs when storing large amounts.

Common Mistakes to Avoid

Assuming 1000 GB = 1 TB exactly

In binary, 1 TB = 1024 GB. Using 1000 gives a 2.4% error.

Use 1024 for accurate binary conversion, or 1000 for marketing approximations.
