Conversion Tools Calculators

Convert units of length, weight, temperature, file size, and number systems.

Conversion is about consistent definitions: pick the same system (binary 1024 vs. decimal 1000 for data sizes) end-to-end before comparing numbers. Unit converters map physical units; file-size tools label KiB/MiB vs KB/MB where relevant. Binary/hex tools show positional notation — they do not validate whether a bit pattern is meaningful for your protocol. Always sanity-check orders of magnitude when a conversion feeds into a real-world decision (storage, nutrition labels, engineering tolerances).

How to choose the right tool

Each tool below has a different purpose, assumptions, and common pitfalls. Read the framing first — the same numbers can mean very different things depending on the formula.

Base Converter

The Binary Converter lets you instantly convert numbers between four number bases: binary (base 2), decimal (base 10), hexadecimal (base 16), and octal (base 8). Type in any of the four fields and all others update automatically. Essential for computer science students, programmers working with memory addresses and bitwise operations, hardware engineers, and anyone learning digital electronics fundamentals. Includes a quick reference for common conversions and the relationship between bits, bytes, and hex values.

File Size Converter

The File Size Converter lets you convert between all common digital storage units: bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB). Choose between binary (base-2: 1 KB = 1,024 bytes) and decimal (base-10 SI: 1 KB = 1,000 bytes) calculation modes, since storage manufacturers use decimal while operating systems use binary — which is why a "1 TB" hard drive shows up as about 931 GB in Windows or macOS. Useful for understanding storage requirements, comparing device capacities, estimating upload/download times, and database storage planning.

Unit Converter

Convert between metric and imperial units across length, weight, temperature, area, and volume with instant results.

Frequently Asked Questions

How do I convert kilograms to pounds?

Use the Unit Converter — select "Weight", enter the value in kilograms, and choose pounds as the target unit. 1 kg ≈ 2.205 lbs.

How do I convert file sizes between bytes and megabytes?

Enter the value in our File Size Converter and select the source and target units. It supports bytes, KB, MB, GB, and TB.

What is the difference between binary and decimal file sizes?

Binary uses powers of 1024 (KiB, MiB, GiB), while decimal uses powers of 1000 (KB, MB, GB). A 1 TB drive holds about 931 GiB in binary.
