BTUs do not convert directly to watts because BTUs measure energy and watts measure power. However, BTUs per hour can be converted to watts; one BTU per hour is approximately 0.293 watts, according to Rapid Tables. Similarly, 10,000 BTUs per hour corresponds to 2,930 watts. Conversely, a single watt converts to approximately 3.412 BTUs per hour. BTUs convert to other units of energy, such as joules. A single BTU is equal to approximately 1,055 joules of energy.
