Frequently Asked Questions
How do I use the converter?
Pick a category, type a value and choose the units — the result updates as you type. You can also type a whole query such as "5 km to miles" or "100 f to c" into the search box.
Is ConvertMe.org free?
Yes. There is no account, no app to install and no premium tier. The values you type are calculated in your browser and never sent to our servers.
How accurate are the conversions?
Units that are defined exactly — such as 1 inch = 2.54 cm, 1 lb = 0.45359237 kg or 1 US gallon = 3.785411784 L — use the exact definition. Results are shown to up to 10 significant digits.
Is a kilobyte 1,000 or 1,024 bytes?
In the SI convention used by drive makers and networking, 1 KB = 1,000 bytes. The binary unit is the kibibyte: 1 KiB = 1,024 bytes. The converter lists both so you can pick the one you need.
Are the currency rates live?
When you open the currency converter, it loads the latest European Central Bank reference rates, which are updated once per working day. They are for reference only; banks and card providers add their own margin.
Can I share a conversion?
Yes. The address bar updates as you convert, so you can bookmark or share a link that reopens the same units and value.
