# Unit Converter MCP Server

A Model Context Protocol server for converting between different units. This server enables LLMs to perform accurate unit conversions across multiple measurement categories.

### Available Tools

- `convert` - Converts between different units.
  - `expression` (string, required): Expression to be converted in the format "value from_unit to to_unit" (e.g., "5.2 m to km" or "500 hz to khz")

### Supported Unit Categories

The converter supports the following categories of units:

1. **Length**: m, km, cm, inch, ft, mile, etc.
2. **Area**: sqm, sqkm, sqft, acre, ha, etc.
3. **Volume**: m3, l, ml, gal, qt, pt, cup, floz, etc.
4. **Mass/Weight**: kg, g, mg, lb, oz, t, st, etc.
5. **Temperature**: celsius (c), fahrenheit (f), kelvin (k)
6. **Energy**: j, kj, cal, kcal, wh, kwh, btu, etc.
7. **Power**: w, kw, mw, hp, btu_h, etc.
8. **Pressure**: pa, kpa, bar, atm, psi, mmhg, etc.
9. **Speed**: m/s, km/h, mph, ft/s, knot, etc.
10. **Time**: s, ms, min, h, day, week, month, year, etc.
11. **Digital Storage**: B, KB, MB, GB, bit, Kb, Mb, Gb, etc.
12. **Fuel Economy**: km/l, mpg, l/100km, etc.
13. **Data Transfer Rate**: bit/s, kbit/s, mbit/s, B/s, MB/s, etc.

## Installation

### Using uv (recommended)

When using [`uv`](https://docs.astral.sh/uv/) no specific installation is needed. We will
use [`uvx`](https://docs.astral.sh/uv/guides/tools/) to directly run *mcp-server-converter*.

```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```

### Using PIP

Alternatively you can install `mcp-server-converter` via pip:

```bash
pip install mcp-server-converter
```

After installation, you can run it as a script using:

```bash
python -m mcp_server_converter
```

## Configuration

### Using uv (recommended)

Add this to your MCP client settings:

```json
"mcpServers": {
  "converter": {
    "command": "uvx",
    "args": ["mcp-server-converter"]
  }
}
```

### Using PIP

Alternatively add this to your MCP client settings:

```json
"mcpServers": {
  "converter": {
    "command": "python3",
    "args": ["-m", "mcp_server_converter"]
  }
}
```

## Supported Unit Conversions

### Length Units
- Meters (m, meter, meters)
- Kilometers (km, kilometer, kilometers)
- Centimeters (cm, centimeter, centimeters)
- Inches (in, inch, inches)
- Feet (ft, foot, feet)
- Miles (mi, mile, miles)

### Frequency Units
- Hertz (hz, hertz)
- Kilohertz (khz, kilohertz)
- Megahertz (mhz, megahertz)
- Gigahertz (ghz, gigahertz)

## Examples

### Length Conversions
- Convert meters to kilometers: `5 m to km` → `0.005`
- Convert miles to kilometers: `1 mile to km` → `1.60934`
- Convert feet to meters: `10 ft to m` → `3.048`
- Convert inches to centimeters: `12 in to cm` → `30.48`

### Frequency Conversions
- Convert hertz to kilohertz: `500 hz to khz` → `0.5`
- Convert kilohertz to megahertz: `1500 khz to mhz` → `1.5`
- Convert hertz to megahertz: `2000000 hz to mhz` → `2`
- Convert gigahertz to megahertz: `2.5 ghz to mhz` → `2500`
