Program to convert speed in km/hr to m/sec and vice versa
Convert speed given in km/hr to m/sec and vice versa .
Examples:
Input : kmph = 72, mps = 10
Output : speed_in_mps = 20
speed_in_kmph = 36
Input : kmph = 54, mps = 15
Output : speed_in_mps = 15
speed_in_kmph = 54
Approach:
1 km = 1000 m and 1 hr = 3600 sec (60 min x 60 sec each).
Conversion from Km/h to m/sec-
When converting km/hr to m/sec, multiply the speed with 1000 and divide the result with 3600.
1 km/hr = 5/18 m/sec or 0.277778 m/sec
Conversion from m/sec to km/h-
When Converting m/sec to km/hr, divide the speed with 1000 and multiply the result with 3600.
1 m/sec = 18/5 km/hr or 3.6 km/hr
Below is the program implementation:
C++
// CPP program to convert // kmph to mps and vice versa #include <bits/stdc++.h> using namespace std; // function to convert speed // in km/hr to m/sec float kmph_to_mps(float kmph) { return (0.277778 * kmph); } // function to convert speed // in m/sec to km/hr float mps_to_kmph(float mps) { return (3.6 * mps); } // driver function int main() { // variable to store // speed in kmph float kmph = 72.0; // variable to store // speed in mps float mps = 10.0; cout << "speed_in_mps = " << kmph_to_mps(kmph) << " speed_in_kmph = " << mps_to_kmph(mps); return 0; } |
