The k factor, or thermal conductivity, for copper at 68 degrees Fahrenheit (20 degrees Celsius) is typically around 401 W/m·K (watts per meter per kelvin). This value can vary slightly depending on the purity of the copper and the specific temperature conditions, but it remains relatively consistent for standard applications. Copper's high thermal conductivity makes it an excellent choice for electrical and thermal applications.
20 degrees Celsius is 68 degrees Fahrenheit; but I like it cooler than that in the Winter.
0.11 x 68 = 7.48
For basic settings, and best results, set your temp. for cooling at about 75 degrees F. or at the highest possible temp. that you can and still be comfortable. The same is true for the temp. setting for heating mode except in reverse. For heating, about 68 to 70 degrees is normal or the lowest temp. possible. This will allow your A/C to run less and operate more efficiently.

The equation for amperage when the kilowatts are known is Amps = kVA x 1000/1.73 x Volts.The electrical code states that a feeder for a transformer has to be rated at 125% for the primary and secondary load amperages.The amperage on the primary needed to supply a 70 KVA three phase transformer to its full capacity at 600 will be 68 amps. 68 x 125% = 85 amps. A #4 copper conductor with an insulation factor of 90 degrees C is rated at 95 amps.The amperage on the secondary needed to supply a 70 KVA three phase transformer to its full capacity at 480 will be 84 amps. 84 x 125% = 105 amps. A # 3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.
68 degrees Celsius is 154.4 degrees Fahrenheit.
68 degrees Fahrenheit = 20 degrees Celsius
68 degrees Fahrenheit is equivalent to 20 degrees Celsius.
68 is.
68 degrees Fahrenheit is 20 degrees Celsius.
20 degrees Celsius = 68 degrees Fahrenheit
Since the scale for 68 is not specified it is taken to be the absolute scale. 68 degrees K is -205.15 degrees C
68 degrees Fahrenheit = 20 degrees Celsius
68 degrees Fahrenheit = 20 degrees Celsius
68 degrees Fahrenheit is approximately 20 degrees Celsius.
20 degrees Celsius = 68 degrees Fahrenheit.
