WebThe Americans use BTUs per hour instead of Watts (a BTU is a British Thermal Unit!), square feet instead of square metres, and degrees Farenheit instead of Centigrade or Kelvin. So their unit for R-value is hr-ft2-°F/Btu. Now 1 m2.K/W = 5.678 hr-ft2-°F/Btu So, to convert from the SI R-value to the American R-value, multiply by 5.678.
