In short
How many bits is 80 bytes?
80 B = 640 bit. 1 byte = 8.000000 bits, so the working is 80 × 8.000000 = 640.
The working
The factor below is an exact definition rather than a measurement, so nothing is approximated in the arithmetic. The only rounding on this page happens where a number is displayed.
1 byte = 8.000000 bits 80 × 8.000000 = 640
How much precision do you need?
Each row is the same answer cut at a different number of decimals, with what that choice costs you. Pick the shortest row whose error is smaller than whatever you are measuring with.
| Rounded to | Answer (bit) | Off by |
|---|---|---|
| Whole number | 640 | exact |
| 1 decimal | 640.0 | exact |
| 2 decimals | 640.00 | exact |
Round trip: take 640 bit back the other way and you land on 80.0000 B — a drift of 0.0000 B. That gap is the rounding, not the conversion.
Frequently asked questions
What is 80 bytes in bits?
80 bytes is 640 bits. 1 byte = 8.000000 bits, so the working is 80 × 8.000000 = 640.
How accurate is 640 bit?
Rounding to 640 bit and converting straight back gives 80.0000 B, a drift of 0.0000 B from the 80 you started with. The factor itself is exact; every bit of that difference comes from the rounding, not the conversion.
