Data Unit Converters

Every tool on this page converts between the two ways the digital world measures data: bits (used by networks and internet plans) and bytes (used by files, apps and operating systems). All calculators run in real time, support decimal (SI) and binary (IEC) standards where relevant, and follow our published calculation methodology.

Speed Converters

⚡

Mbps to Bytes Converter

Convert megabits per second to Bytes/s, KB/s and MB/s — see the real download speed behind your internet plan.

⇄

Bytes to Mbps Converter

Convert B/s, kB/s, MB/s, KiB/s or MiB/s to Mbps and back with exact SI/IEC factors.

🚀

Mbps to MB/s Converter

See your plan's real download speed — 100 Mbps = 12.5 MB/s. With MiB/s support and plan comparison.

🌐

Mbps to Gbps Converter

Convert Mbps to Gbps or Gbps to Mbps exactly — 1,000 Mbps = 1 Gbps, with MB/s and line-rate context.

🎵

Mbps to Kbps Converter

Convert Mbps to Kbps or Kbps to Mbps with exact ×1,000 and ÷1,000 formulas and bitrate examples.

🔢

Bits to Bytes Converter

8 bits = 1 byte — the foundation under every speed trap, with an interactive byte builder.

Storage Converters

Bytes to MB Converter

Convert bytes to MB and MiB with exact 1,000,000 and 1,048,576 factors, large-number precision, formulas and tables.

📁

KB to MB Converter

1 MB = 1,000 KB — built for upload limits, attachments, and why a "2 MB max" form rejects a 2 MB file.

💾

MB to GB Converter

1 GB = 1,000 MB decimal or 1,024 binary — both standards shown side by side, no guessing.

🗄️

GB to TB Converter

1 TB = 1,000 GB — and what Windows will really show: a 1 TB drive displays as 931 GB.

🧮

GB to GiB Converter

1 GB = 0.9313 GiB — the decimal/binary conversion behind every "smaller drive" mystery, both directions.

Bits vs Bytes: Which Tool Do You Need?

The rule of thumb: if the number comes from your internet provider or a speed test, it's in bits (Mbps). If it comes from a download bar, file manager, or app, it's in bytes (MB/s, KB/s). Since 1 byte = 8 bits, the bit number is always 8× larger than the byte number for the same real speed.

Start from your internet plan (Mbps)?

Convert the advertised speed into the download speed you'll actually see.

→ Mbps to Bytes Converter

Start from an app's speed (MB/s, KB/s)?

Check how much of your plan's bandwidth a download is really using.

→ Bytes to Mbps Converter

Comparing internet plans (Mbps vs MB/s)?

See the real download speed behind every plan tier, from 25 Mbps to gigabit.

→ Mbps to MB/s Converter

Starting from an exact raw file-size count? Use the Bytes to MB converter to compare decimal MB and binary MiB without rounding or unit-label ambiguity. Looking for practical calculators instead — download time, bandwidth, or packets per second? Visit our Network Tools & Calculators.
