The speed of 40 kmph converts to 11.1111 meters per second. This is because when you convert kilometers per hour to meters per second, you multiply by 1000 (meters in a kilometer) and divide by 3600 (seconds in an hour), resulting in a factor of 1/3. So, 40 kmph equals approximately 11.1111 m/s.
To understand this, remember that 1 kilometer equals 1000 meters, and 1 hour equals 3600 seconds. So, kmph is a measure of how many kilometers are traveled in an hour. Converting this to meters per second involves changing kilometers to meters and hours to seconds. The formula is kmph * (1000 / 3600), which simplifies to kmph / 3. If you plug 40 kmph into this, you get 40 / 3, which is approximately 11.1111 meters per second.
Conversion Formula
The conversion from kmph (kilometers per hour) to meters involves multiplying the speed value by 1000 to convert kilometers to meters, then dividing by 3600 to convert hours to seconds. The formula used is: meters per second = kmph * (1000 / 3600). This simplifies to kmph / 3 because 1000 divided by 3600 equals approximately 0.2778. The process ensures the units shift correctly from km/h to m/s, allowing for consistent measurement across different systems. For example, if you have 60 kmph, multiplying by 1000 yields 60,000 meters per hour, and dividing by 3600 gives about 16.6667 meters per second.
Conversion Example
- Convert 50 kmph to meters per second:
- Multiply 50 by 1000 = 50,000 meters per hour
- Divide 50,000 by 3600 = approximately 13.8889 meters per second
- Convert 25 kmph to meters per second:
- Multiply 25 by 1000 = 25,000 meters per hour
- Divide 25,000 by 3600 = approximately 6.9444 meters per second
- Convert 80 kmph to meters per second:
- Multiply 80 by 1000 = 80,000 meters per hour
- Divide 80,000 by 3600 = approximately 22.2222 meters per second
- Convert 10 kmph to meters per second:
- Multiply 10 by 1000 = 10,000 meters per hour
- Divide 10,000 by 3600 = approximately 2.7778 meters per second
- Convert 100 kmph to meters per second:
- Multiply 100 by 1000 = 100,000 meters per hour
- Divide 100,000 by 3600 = approximately 27.7778 meters per second
