Data Converter - KB, MB, GB, TB | Hexa

Understanding Data Storage Units

We encounter data sizes everywhere: file properties, cloud storage quotas, bandwidth limits, and device specifications. A photo might be 3 MB; a video 2 GB; a hard drive 1 TB. But what's the relationship? 1 KB = 1,024 bytes (binary) or 1,000 bytes (decimal). 1 MB = 1,024 KB or 1,000 KB depending on context. Storage manufacturers often use decimal (1 GB = 1 billion bytes) while operating systems use binary (1 GB = 1,073,741,824 bytes). That's why a "1 TB" drive shows as ~931 GB in Windows—the units differ. Our converter supports both conventions so you can match the context. See Byte on Wikipedia for the full picture.

Binary vs Decimal: Why It Matters

Binary (base 2): 1 KB = 1,024 B, 1 MB = 1,024 KB, 1 GB = 1,024 MB. Used by operating systems (Windows, macOS, Linux) and many software tools. Aligns with how computers address memory.

Decimal (base 10): 1 KB = 1,000 B, 1 MB = 1,000 KB, 1 GB = 1,000 MB. Used by storage manufacturers, network providers, and some cloud services. Easier for marketing ("1 TB" sounds bigger).

When comparing storage or bandwidth, ensure you're using the same convention. Our converter handles both.

Common Conversion Scenarios

File sizes: "How many MB is this 500 MB file?"—sometimes you need GB or KB for reporting or limits.

Bandwidth: Data caps are often in GB. Convert your usage to understand how much you've consumed.

Cloud storage: Plans are sold in GB or TB. Convert to compare offers or estimate how many files you can store.

Development: Configuring upload limits, buffer sizes, or API payload limits often requires precise byte conversions.

Privacy and Performance

All conversions run locally in your browser. We don't store or transmit your inputs. The tool works offline—no server dependency. Instant results, no signup.
