## Get Started

The Calculator is a special command. It's always available in [Root Search](https://manual.raycast.com/search-bar) — just type any expression. You'll see your expression displayed on the left, and the answer on the right.

## What Raycast Understands

The Calculator solves complex math expressions and supports time zones, unit conversions, dates, and currencies. Expressions now show with syntax highlighting so they're easier to read at a glance.

- Convert units and currencies like a breeze. For example, type `10ft in m` or `100 usd in gbp`.
- Get the % between two different values. For example, type `52% of 900`.
- Check the time of your teammates in different time zones. For example, type `5pm ldn in sf` or `time in tokyo`.
- Get the date for your next event, like `monday in 3 weeks`.
- Find out how many days are left in the quarter, like `days until 31 Mar`.
- Answer math questions like `square root of 625` or `2 power 10`.
- Convert a duration into a human-readable timespan, like `145 mins to timespan`.
- Plan your work week. For example, type `workhours in 2023` or `55h in workdays`.
- Convert sizes for design work. For example, type `2 inches in px at 72 ppi`.
- Solve advanced trigonometry, including `cot`, `csc`, and their hyperbolic and inverse variants like `sinh` or `acos`.
- Compare the time between you and a teammate. For example, type `time diff Paris` or the shortcut `diff Paris`.
- Find out what time it'll be after a delay. For example, type `time in 4 hours` or `time in 4 hours in San Francisco`.
- Add time to a city's clock and the answer stays in that city's time zone. For example, type `time in brisbane + 4 hours` — this holds even across a daylight saving change.
- Work with ISO 8601 timestamps in Zulu format, like `2024-03-15T14:30:00Z`.
- Add days or hours to a date. For example, type `August 5 + 5` for days or `3:45pm + 5` for hours.
- Work out a discount. For example, type `20% off 80`.
- Write currency in shorthand. For example, type `USD1K` or `10K`.
- Look up times in cities, airports, and tourist destinations — including multi-word names like `time in São Paulo` or `time in JFK`.
- Type `now`, `today`, `tomorrow`, `yesterday`, or `time` on its own in Root Search to get the date or time straight away.
- Convert CSS units to pixels and back. For example, type `2rem in px` or `32px in rem`. Set how many pixels 1 rem or em equals in [Settings](#settings).

## Color Conversion

Type a color value in Root Search to preview it and copy it in another format. Raycast recognizes:

- Hex, like `#ff6363`, including 3, 4 and 8 digit values
- `rgb()` and `rgba()`, like `rgb(255, 99, 99)` or `rgb(255 99 99 / 50%)`
- `hsl()` and `hsla()`, like `hsl(0 100% 69%)`
- `hwb()`, `lab()`, `lch()`, `oklab()` and `oklch()`

Press `↵` on the result to open **Copy Color as…** and choose a format: Hex, Hex with Alpha, RGBA, RGBA (Percentage), RGB (CSS4), HSL, HSL with Alpha, HSL (CSS4), HWB, Lab, LCH, Oklab, Oklch, NSColor (macOS) or UIColor (iOS).

Color names such as `red` aren't converted, so they don't get in the way of your other searches.

## Keyboard Shortcuts

- `↵` to copy the answer to your clipboard
- `⌘ ↵`/`Ctrl ↵` to paste the answer into the active app
- `⌥ ⌘ C`/`Ctrl Alt C` to copy the unformatted answer to your clipboard
- `⌥ ⇧ ⌘ C`/`Ctrl Alt Shift C` to copy the question and answer to your clipboard

## Settings

Open **Settings → Extensions → Calculator** to configure the Calculator:

- **Syntax highlighting**: Color the parts of an expression so it's easier to read. On by default.
- **Enable Color Conversion**: Preview and convert color values from Root Search. On by default.
- **REM/EM to Pixel Conversion**: The number of pixels equivalent to 1 rem or em. Defaults to 16.

### Decimal Separator

The decimal separator used in the Raycast calculator is set by your system. If you want, you can change this.

1. Open your system settings and choose **Language and Region**.
2. Select **Number format** and set your preferred decimal separator and number grouping separator.
3. Your changes will be available immediately in the Raycast calculator. If they aren't, restart Raycast.
