• Feet per Second (ft/s)

What is Speed?

Speed is a measure of how quickly an object moves over a distance within a specific time. It is a key concept in physics, transportation, navigation, sports, and many other fields. Depending on the context, different units of speed are used—some based on land measurement systems, others for air and sea travel.

Speed = Distance / Time

The SI unit of speed is meters per second (m/s), but units like kilometers per hour (km/h), miles per hour (mph), and knots are commonly used around the world. Understanding how to convert between these units ensures precision and clarity in communication and analysis.

Here are a few useful conversion relationships:

• 1 Kilometer per Hour = 0.621371 Miles per Hour
• 1 Mile per Hour = 1.60934 Kilometers per Hour
• 1 Knot = 1.15078 Miles per Hour
• 1 Meter per Second = 3.6 Kilometers per Hour
• 1 Foot per Second ≈ 0.3048 Meters per Second

With the Speed Converter, there’s no need to remember formulas or conversion factors. Just enter your value and get accurate, instant results—making your calculations faster and more reliable.

What Are the Supported Speed Units in Our Speed Converter?

Our Speed Converter allows you to easily convert between the most commonly used units of speed or velocity in fields like transportation, aviation, physics, and sports. Whether you’re calculating the pace of a vehicle, the speed of a runner, or measuring velocity in scientific terms, this tool ensures accurate results across all units.

Below is a full list and explanation of the supported speed units available in our tool to help you convert values quickly and accurately:

1. Kilometers per Hour (km/h)

Kilometers per hour is the most common unit of speed used globally, especially for road speed limits. It measures the number of kilometers traveled in one hour.

2. Miles per Hour (mph)

Miles per hour is used primarily in the United States and a few other countries to indicate vehicle speed. 1 mph = 1.60934 km/h.

3. Knots (nautical miles per hour)

Knot is used in maritime and aviation industries. It measures speed in nautical miles per hour. 1 knot = 1.852 km/h.

4. Meters per Second (m/s)

Meters per second is the SI unit for speed or velocity. It is commonly used in scientific calculations and engineering.

5. Centimeters per Second (cm/s)

Centimeters per second is used to measure very slow speeds, often in physics, fluid dynamics, and biological studies. 1 m/s = 100 cm/s.

6. Feet per Second (ft/s)

Feet per second is commonly used in the U.S. for measuring speed in engineering or ballistics. 1 ft/s = 0.3048 m/s.

Speed Conversion Formulas

How to Convert Speed Units? – Explained with Examples

Speed conversions are essential in transportation, science, sports, and engineering. Whether you’re comparing driving speeds or converting nautical measurements, this guide will help you convert between popular speed units using clear formulas and practical examples.

1. How to Convert Kilometers per Hour to Meters per Second?

To convert km/h to m/s, divide by 3.6. Formula: m/s = km/h ÷ 3.6 Example: 90 km/h ÷ 3.6 = 25 m/s

2. How to Convert Miles per Hour to Kilometers per Hour?

To convert mph to km/h, multiply by 1.60934. Formula: km/h = mph × 1.60934 Example: 60 mph × 1.60934 = 96.56 km/h

3. How to Convert Knots to Kilometers per Hour?

To convert knots to km/h, multiply by 1.852. Formula: km/h = knots × 1.852 Example: 10 knots × 1.852 = 18.52 km/h

4. How to Convert Meters per Second to Feet per Second?

To convert m/s to ft/s, multiply by 3.28084. Formula: ft/s = m/s × 3.28084 Example: 5 m/s × 3.28084 = 16.4 ft/s

5. How to Convert Centimeters per Second to Meters per Second?

To convert cm/s to m/s, divide by 100. Formula: m/s = cm/s ÷ 100 Example: 250 cm/s ÷ 100 = 2.5 m/s

6. How to Convert Feet per Second to Miles per Hour?

To convert ft/s to mph, multiply by 0.681818. Formula: mph = ft/s × 0.681818 Example: 30 ft/s × 0.681818 = 20.45 mph
