## Overview

Quickly convert speed values from miles per hour (MPH) to meters per second (M/S) with customizable decimal precision. This tool provides instant, highly accurate conversions using the standard SI factor of 1 mph = 0.44704 m/s, outputting clean JSON data perfect for developers, engineers, and physics calculations.

## Inputs

- **Miles per hour** (text): e.g. 60
- **Decimal Precision** (number)

## When to use

- When translating vehicle speeds from imperial units (MPH) to metric SI units (M/S) for scientific research or engineering reports.
- When processing telemetry data from automotive sensors that output speed in miles per hour.
- When solving physics or kinematics problems that require speed inputs to be in standard meters per second.

## How it works

- Enter the speed value in miles per hour (MPH) into the input field.
- Adjust the decimal precision to your preferred rounding limit between 0 and 10 decimal places.
- Click convert to instantly generate the result in meters per second (M/S) formatted as a JSON object.

## Use cases

- Converting speed limits from US/UK road signs to metric units for international navigation software.
- Standardizing wind speed measurements from meteorological stations reporting in MPH to M/S for weather models.
- Normalizing telemetry data from racing simulators or vehicle data loggers for aerodynamic analysis.

## Frequently asked questions

### What conversion factor is used to convert MPH to M/S?

The tool uses the exact standard conversion factor where 1 mph equals 0.44704 meters per second.

### Can I control the decimal precision of the output?

Yes, you can configure the decimal precision from 0 up to 10 decimal places to suit your calculation requirements.

### What is the default decimal precision if not specified?

The default precision is set to 4 decimal places.

### Is this tool suitable for batch telemetry data conversion?

Yes, it outputs structured JSON, making it easy to integrate the converted values directly into your data pipelines or code.

### Does this tool support negative speed values?

Yes, you can input negative values to represent velocity vectors or reverse speeds.
