Convert meters to miles:

#include <stdio.h>
#include <math.h>

int main(void)
{
  float meter, mile;
  printf("Meter input: ");
  scanf("%f", &meter);
  mile = meter * 0.000621371;
  printf("Mile output: %5.2f", mile);

  return 0;
}

Convert Celsius to Rankine:

#include <stdio.h>
#include <math.h>

int main(void)
{
  float Celsius, Rankine;
  printf("Celsius input: ");
  scanf("%f", &Celsius);
  Rankine = (Celsius * 1.8) + 491.67;
  printf("Rankine output: %5.2f", Rankine);

  return 0;
