Convert Terabytes to Bits
TB to b · digital storage conversion
What are terabytes and bits?
A terabyte is one trillion bytes, the typical capacity of a modern hard drive. A bit is the smallest unit of digital data, a single 0 or 1. For scale: a photo is a few MB, an HD movie a few GB, and a modern drive holds 1 TB or more. These use decimal (1 KB = 1,000 bytes).
How to convert terabytes to bits
1 TB = 8,000,000,000,000 b. To convert, multiply the number of terabytes by 8,000,000,000,000. For example, 5 TB = 40,000,000,000,000 b, and 20 TB = 160,000,000,000,000 b. To go the other way, multiply bits by 1.2500e-13 (since 1 b = 1.2500e-13 TB).

FAQ
What is 1 TB in b?
1 TB = 8,000,000,000,000 b. To convert any amount, multiply the number of terabytes by 8,000,000,000,000.
How do I convert bits back to terabytes?
Go the other way: 1 b = 1.2500e-13 TB, so multiply bits by 1.2500e-13 to get terabytes.
Is a terabyte bigger than a bit?
Yes — 1 TB is the larger unit, equal to 8,000,000,000,000 b.
Are these digital storage conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
