UniConv – Unit & Currency Converter bởi PROVIDER

Select a price, a measurement, a color or a time, right-click, choose UniConv: it reads the amount and unit, opens the right converter and shows the result. 27 converters, live currency rates, no account, no tracking.

Stop opening a new tab every time you see a price in another currency or a measurement in another unit. UniConv converts it right where you are.

HOW IT WORKS
Select text on any page, such as "USD 56.231", "12.5 km" or "-5°C", then right-click and choose UniConv. It reads the amount and the unit, opens the right converter in the popup or the sidebar, fills in the fields and shows the result. If the selection can't be converted, you get a short "not supported" message instead.

WHAT YOU CAN CONVERT
UniConv includes 27 converters, and every one works both ways as you type:
- Money: currencies with live exchange rates, and popular cryptocurrencies.
- Everyday units: length, weight, volume, temperature, area, speed, time, energy, power, pressure and more.
- Running pace, fuel economy, data sizes and data transfer rates.
- Medical: common blood test values and blood pressure units, as a quick reference.
- Screen resolution, geographic coordinates and colors, with a round color preview that opens the color picker.
- Dates between calendars, number bases and time zones, with daylight saving included.

FEATURES
- Understands currency symbols, currency codes, words like "dollars", and both 1,234.56 and 1.234,56.
- Live rates from the source you choose (Frankfurter, ExchangeRate-API or Currency-API), cached for an hour for offline use, with a clear notice when rates are stale.
- Multi-currency mode: convert one amount into several currencies at once and reorder them by drag and drop.

- One-click copy on every value field, and each tool remembers your last units.
- Also available as a website with the same converters.

PRIVACY
No account, no analytics, no tracking, no data collection. The add-on only contacts the exchange-rate and crypto-price service you select, to download rates. The text you select and the amounts you type are processed locally and never leave your browser. Full policy on the UniConv website (Privacy page).

PERMISSIONS
- Context menus: adds the right-click "UniConv" menu.
- Storage: saves your settings and cached rates on your device.
- Alarms: refreshes cached rates once an hour.
- Clipboard write: powers the copy buttons.
- Active tab / Scripting: only when you right-click an unsupported selection, shows a small message on the current page. The page's content is not read.
- Access to the rate and price services you choose.

Lab values and pressure conversions are a reference tool, not medical advice.
