Live exchange rates and everyday unit conversions — all in one place, completely free.
Converting currencies and units accurately matters for a lot more than casual curiosity — travelers need to know what a price actually costs in their home currency, online shoppers compare prices across countries, students and engineers convert between metric and imperial measurements for schoolwork and projects, and international senders need to know how much money will actually arrive on the other end. UnitConvertly brings live currency exchange rates and everyday unit conversions together in one free, no-sign-up tool.
A currency exchange rate expresses how much of one currency is needed to buy one unit of another. To convert an amount, you multiply it by the current exchange rate: for example, if 1 USD equals 278 PKR, then $100 converts to 27,800 PKR (100 × 278). Exchange rates fluctuate constantly based on economic conditions, interest rates, and market demand, which is why UnitConvertly pulls live rate data and updates daily rather than relying on a fixed conversion table. It's also worth knowing that the rate you see on a converter is typically the mid-market rate — the midpoint between buy and sell prices — while banks and money transfer services usually add their own margin or fee on top, so the amount you actually receive when sending money abroad is often slightly less favorable than the headline rate.
Unit conversion follows a similar principle: every unit within a category (length, weight, temperature, volume, and so on) has a defined relationship to a base unit, and converting between two units means multiplying or dividing by the appropriate conversion factor. For most unit categories, this is a simple multiplication — for example, converting kilometers to miles multiplies by roughly 0.6214. Temperature is a notable exception, since Celsius, Fahrenheit, and Kelvin scales don't share a common zero point, so temperature conversions require addition or subtraction as well as multiplication (for example, °F = °C × 9/5 + 32).

Why does the exchange rate I see differ slightly from my bank's rate?
Converters typically display the mid-market exchange rate, while banks and remittance services usually add a margin or fee on top, meaning the rate you get when actually sending or exchanging money is often slightly less favorable than the reference rate shown here.
