1. What is m/s to km/h Conversion?

The conversion between meters per second (m/s) and kilometers per hour (km/h) is a common unit conversion in physics and engineering. It's used to express speed in different measurement systems.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( m/s \) — Speed in meters per second
• \( 3.6 \) — Conversion factor (3600 seconds/hour ÷ 1000 meters/kilometer)

Explanation: Since 1 kilometer equals 1000 meters and 1 hour equals 3600 seconds, the conversion factor is derived from (1000 m/km)/(3600 s/h) = 1/3.6 (m·h)/(km·s).

3. Importance of Speed Conversion

Details: Different fields use different units - m/s is common in scientific contexts while km/h is standard for vehicle speeds in most countries. Accurate conversion is essential for proper interpretation and comparison of speed measurements.

4. Using the Calculator

Tips: Simply enter the speed in meters per second (must be ≥ 0) and click "Convert". The result will show the equivalent speed in kilometers per hour.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.6?
A: Because 1 m/s equals 3.6 km/h (1 km = 1000 m and 1 h = 3600 s, so 1 m/s = (1/1000 km)/(1/3600 h) = 3.6 km/h).

Q2: How do I convert km/h back to m/s?
A: Divide km/h by 3.6 or multiply by 0.277778 (1/3.6).

Q3: What are typical m/s values in everyday life?
A: Walking speed is about 1.4 m/s (5 km/h), running ~3-5 m/s, highway speed ~28 m/s (100 km/h).

Q4: Which unit is better for scientific work?
A: m/s is preferred in physics as it's the SI unit, directly relating to other metric units.

Q5: Are there other speed units I might need to convert?
A: Yes, common ones include miles per hour (mph), knots (nautical miles per hour), and feet per second (fps).
