## Overview

This tool converts geographic coordinates (latitude and longitude) into the Maidenhead locator system, a grid-based code commonly used by amateur radio operators to specify locations for communication and logging.

## Inputs

- **Latitude** (number): Enter latitude (-90 to 90)
- **Longitude** (number): Enter longitude (-180 to 180)

## When to use

- When you need to determine your Maidenhead grid square for amateur radio contacts or contests.
- When converting GPS coordinates to a standardized locator format for mapping or station setup.
- When planning radio operations that require precise grid square information for logging or coordination.

## How it works

- Enter the latitude value between -90 and 90 degrees in the designated field.
- Enter the longitude value between -180 and 180 degrees in the designated field.
- The tool processes the inputs and outputs the corresponding Maidenhead locator code in JSON format.

## Use cases

- Amateur radio operators sharing their grid square during contests or daily communications.
- Logging contacts in radio logs where Maidenhead locators are required for record-keeping.
- Integrating coordinate data into software or maps that utilize the Maidenhead system for location referencing.

## Frequently asked questions

### What is a Maidenhead locator?

A Maidenhead locator is a grid-based system used to represent geographic locations, primarily in amateur radio for specifying positions.

### How accurate is the conversion?

The conversion is precise based on the input coordinates, generating a standard 6-character Maidenhead code.

### Can I use this for locations outside Earth?

No, this tool is designed only for Earth-based coordinates within the specified latitude and longitude ranges.

### What format does the output use?

The output is provided in JSON format, containing the Maidenhead locator string derived from the coordinates.

### Are there any limitations on input values?

Yes, latitude must be between -90 and 90, and longitude between -180 and 180; values outside these ranges are not supported.
