About This Unit Converter

A unit converter translates a number from one measurement system into another. In everyday life, we constantly switch between systems: centimeters on a ruler, inches on a product box, kilograms on a grocery scale, pounds on a fitness app, and gigabytes on a phone. When you want a quick and accurate answer, converting by hand can be slow and error-prone. This Unit Converter helps you convert common units instantly with clear results.

The goal is fast, reliable, and simple. That's why this converter focuses on categories most people search for: length, weight (mass), temperature, area, volume, speed, time, and digital storage (data). You choose a category, enter a value, pick a "from" unit and a "to" unit, and you get the converted result in a readable format.

Why Conversions Matter

Conversions are more than "nice to have." They can change decisions: how much material to buy for a project, whether luggage is within airline limits, how hot an oven should be, or how much storage you need for videos. Mistakes often come from confusing similar-looking units or missing a prefix. This page reduces those mistakes by applying the correct formulas automatically.

Quick examples: 2.54 cm = 1 inch (screen sizes) | 1 kg = 2.205 lb (fitness, shipping) | 1 GB = 1024 MB (computing)

Temperature Conversions

Temperature is different from most conversions because it is not only a multiplier; it has an offset. That's why "swap and multiply" doesn't work here. The common formulas are: F = (C x 9/5) + 32 and C = (F - 32) x 5/9. Kelvin is often used in science: K = C + 273.15. Our converter applies the correct formula automatically and displays it in the details panel.

Data Size Conversions

Data sizes are confusing because two standards exist: decimal (powers of 1000) and binary (powers of 1024). Many operating systems and storage marketing use different definitions. To keep this tool consistent and practical for everyday use, this converter uses the common computing approach: 1 KB = 1024 bytes, 1 MB = 1024 KB, and so on. For network speeds, you may also see bits (Kb, Mb, Gb) rather than bytes (KB, MB, GB). This converter includes both.

How to Use the Converter

1) Choose the category (length, weight, temperature, etc.). 2) Type the value (decimals are allowed). 3) Select "from" and "to" units. 4) Pick precision if needed. 5) Click Convert. You can also swap units instantly, copy the result, or reset the form. The details panel explains the conversion path and provides quick equivalents.

FAQ

Is this converter accurate?
Yes. We use standard conversion factors and formulas. Temperature uses the correct offset + scale. You can increase precision for more decimal places when needed.
Why is temperature conversion different?
Because C to F isn't a simple multiplier. It needs an offset (adding/subtracting 32) and a scale (x9/5 or x5/9). The details section shows the exact formula used.
Do you use 1000 or 1024 for KB/MB/GB?
For practicality we use the common computing approach: 1 KB = 1024 bytes, 1 MB = 1024 KB, etc. Marketing sometimes uses 1000.
Can I copy the result?
Yes. Click "Copy result" and it will copy the converted value to your clipboard (if your browser allows it).
What precision should I choose?
For daily use, 2-3 decimals are enough. Use 4-6 decimals for scientific work or very small values.
Why does my storage show less than advertised?
Different systems use different definitions (1000 vs 1024), and file system overhead can reduce usable space. This tool uses 1024 steps for KB/MB/GB/TB.
