## Overview

Convert miles to kilometers instantly with configurable precision. This utility transforms imperial distance measurements into metric units, allowing you to specify exact decimal placement for calculations, documentation, or technical specifications.

## Inputs

- **Miles** (text): e.g. 26.2
- **Decimal Precision** (number)

## When to use

- Converting running, cycling, or racing distances from imperial to metric units for international events
- Translating vehicle odometer readings for cross-border shipping documentation or automotive exports
- Transforming map measurements or geographic data for engineering and surveying projects

## How it works

- Enter the distance value in miles using standard numeric format (supports integers and decimals)
- Specify your desired decimal precision between 0 and 10 places (defaults to 4 for general use)
- Receive the converted distance in kilometers as structured JSON output containing both original and converted values

## Use cases

- Marathon and road race planning requiring kilometer markers for international participants
- Automotive logistics and export documentation requiring metric odometer readings
- Aviation and nautical chart conversions for flight planning and maritime navigation

## Frequently asked questions

### What conversion formula does the tool use?

The tool multiplies the mile value by 1.609344 to calculate the exact kilometer equivalent.

### Can I enter fractional or decimal mile values?

Yes, the tool accepts decimal inputs such as 26.2 or 13.1 for precise race distance conversions.

### What is the maximum number of decimal places available?

You can configure precision up to 10 decimal places for specialized scientific or technical requirements.

### Does the tool support batch conversion of multiple values?

No, the tool processes single distance conversions; enter values individually for each calculation.

### Is there a limit to how large a number I can convert?

The tool handles standard numeric inputs; extremely large values should be verified against your specific use case requirements.
