About Converting YB to Megabits
YB and Megabit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: YB digital storage unit, and megabit digital storage unit.
Formula
megabits = yb × 8e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 yb equals 8e+24 base units, and 1 megabit equals 1000000 base units, so dividing one by the other gives the direct yb-to-megabit factor of 8e+18.
Simple example
1 YB × 8e+18 = 8e+18 Mb
1 yb = 8e+18 megabits.
Real-world example
500 YB × 8e+18 = 4e+21 Mb
500 yb = 4e+21 megabits.
Conversion table
| YB (YB) | Megabit (Mb) |
|---|---|
| 1 YB | 8e+18 Mb |
| 8 YB | 6.4e+19 Mb |
| 16 YB | 1.28e+20 Mb |
| 64 YB | 5.12e+20 Mb |
| 256 YB | 2.048e+21 Mb |
| 1,000 YB | 8e+21 Mb |
Reverse conversion: Megabit to YB
8e+18 Mb × 1.25e-19 = 1 YB
8e+18 megabits = 1 yb.
yb = megabits × 1.25e-19

Understanding the YB (YB)
YB digital storage unit.
Understanding the Megabit
Megabit (Mb) measures digital storage/transfer. A megabit is 1,000,000 bits (125,000 bytes) under the decimal convention used for network speeds. It is classified as a Decimal (SI-prefixed) digital unit.
Where it's used: Used worldwide for network and internet speed ratings
Megabits vs. megabytes. Internet speeds are quoted in megabits per second (Mbps), while file sizes are quoted in megabytes (MB) — 8 megabits equal 1 megabyte, so a '100 Mbps' connection downloads at up to about 12.5 MB per second.
Uses of the Megabit today
- Internet connection speed advertising (Mbps)
- Network bandwidth measurement
History of the Megabit
Network speeds have conventionally been quoted in bits rather than bytes since early telecommunications measured signal rate in bits per second; this convention carried into modern internet service marketing, which is why connection speeds (Mbps) and file sizes (MB) use different base units, a frequent source of consumer confusion.
Historical origin. Megabit was not the invention of a single named person; it developed through the process described above.
Megabit — sources
- IEC 80000-13 — Defines bit-based units distinct from byte-based units.

Frequently asked questions
How many megabits are in 1 yb?
1 yb equals 8e+18 megabits, using the exact defined conversion factor rather than an estimate.
How do I convert yb to megabit?
Multiply the yb value by 8e+18. The converter above does this instantly to whatever precision you set.
How do I convert megabit back to yb?
Use the reverse factor: 1 megabit equals 1.25e-19 yb. You can also use the swap control in the converter above to flip the direction instantly.
What is a yb?
YB (YB) is a unit of digital storage.
What is a megabit?
Megabit (Mb) measures digital storage/transfer. A megabit is 1,000,000 bits (125,000 bytes) under the decimal convention used for network speeds. It is classified as a Decimal (SI-prefixed) digital unit.
Is the yb to megabit conversion exact?
Yes. Both yb and megabit are defined by fixed standards rather than physical artifacts, so the factor of 8e+18 used above is exact to as many digits as you choose to display.
What is the difference between megabits vs. megabytes?
Internet speeds are quoted in megabits per second (Mbps), while file sizes are quoted in megabytes (MB) — 8 megabits equal 1 megabyte, so a '100 Mbps' connection downloads at up to about 12.5 MB per second.
