## Overview

The Tennis Serve Speed Calculator allows you to determine the velocity of a tennis serve by measuring the distance traveled and the time elapsed from the moment of impact to the point of landing.

## Inputs

- **Distance** (number): Enter distance
- **Unit** (select)
- **Time (seconds)** (number): Enter time

## When to use

- When analyzing your serve performance during practice sessions.
- When comparing the speed of different serve techniques or equipment.
- When you have recorded video footage and need to calculate speed based on known distance and time intervals.

## How it works

- Enter the distance between the baseline and the service impact point.
- Select your preferred unit of measurement, either meters or feet.
- Input the time in seconds it took for the ball to travel that distance.
- Click calculate to receive the speed output in both miles per hour (mph) and kilometers per hour (kmh).

## Use cases

- Tracking improvement in serve speed over several weeks of training.
- Evaluating the impact of different racket tensions on ball velocity.
- Coaching players by providing objective data on their serve power.

## Frequently asked questions

### What is the standard distance for a tennis serve?

The standard distance from the baseline to the service line is 23.77 meters (78 feet).

### How accurate is this calculator?

The accuracy depends entirely on the precision of your time measurement. Using high-speed video analysis provides the most reliable results.

### Does this tool account for air resistance?

No, this calculator provides an average speed based on the linear distance and time provided, assuming constant velocity.

### Can I use this for other sports?

While designed for tennis, it can be used for any sport where you need to calculate the average speed of an object over a known distance.

### What units are supported?

You can input distance in either meters or feet, and the tool will output the calculated speed in both mph and kmh.
