If you’ve ever purchased a 1GB data bundle on Safaricom and wondered why it shows up as 1024MB instead of a clean 1000MB, you’re not alone. Many Kenyan consumers have raised this question, especially when trying to understand how mobile data is calculated and why the numbers don’t seem to align with everyday counting. The answer lies in the fascinating difference between how humans count and how computers calculate digital information.
Digital data is measured using two different systems — the binary system and the decimal system. While everyday measurements such as kilograms, litres, and kilometres use the decimal system (base 10), computers function using the binary system (base 2), which is based purely on ones and zeros.
In the binary world, data is structured in powers of 2, not 10. That means storage and data units increase exponentially based on binary conversions. For example, 1 Kilobyte (KB) equals 1024 bytes, not 1000. Similarly, 1 Megabyte (MB) equals 1024KB, and therefore, 1 Gigabyte (GB) equals 1024MB.
Why 1024 and not 1000?
The number 1024 is special because it is a result of 2 raised to the power of 10 (2¹⁰ = 1024). Computers rely on this format because it aligns perfectly with how memory and processing structures are built — in binary blocks. This structure has been in place since the birth of computer engineering, and it continues to govern how data is measured globally.
So why the confusion?
The conflict arises because storage manufacturers — such as companies that make smartphones, memory cards, and flash disks — often use the more familiar decimal system in marketing. In the decimal system:
- 1GB = 1000MB
- 1MB = 1000KB
This looks neat, simple, and easy to sell — but it’s not how your phone or computer interprets it internally.
So when you buy a 64GB phone, the phone calculates the capacity using binary values. The real usable storage ends up showing much lower than the advertised value — one of the most common frustrations among mobile users.
What does this mean for Safaricom subscribers?
Safaricom, like most mobile networks around the world, uses the binary measurement standard for data. Therefore, when a customer buys:
- 1GB bundle → they receive 1024MB
- 2GB bundle → they receive 2048MB
- 10GB bundle → they receive 10,240MB
This isn’t a case of Safaricom giving extra data — it’s the accurate value of 1GB in computing terms.
However, because consumers generally assume that 1GB equals 1000MB, many believe the telco might be offering a bonus or using tricky data conversions. In reality, customers are getting precisely what the digital system defines as 1GB.
Why doesn’t Safaricom switch to the 1000MB system?
Doing so would cause even more confusion, especially when devices calculate data usage in binary. Your smartphone does not track how much data you use in decimal units. So if data bundles were set using the decimal system, your usage meter would appear to “use up” data much faster, leading to more customer complaints.
Sticking to binary keeps the system precise and uniform — both in data issuance and in data consumption monitoring.
The big takeaway
This entire debate highlights the gap between human-friendly numbers and machine-friendly calculations. Here’s a quick summary:
| Measurement System | Used By | 1GB Equals |
|---|---|---|
| Binary (base-2) | Computers, networks | 1024MB |
| Decimal (base-10) | Marketing, promotions | 1000MB |
So the next time you buy data bundles on Safaricom and see 1024MB displayed for a 1GB purchase, rest assured — you are not being shortchanged. In fact, this is the true representation of 1GB in digital communication technology.
