About These Units
BTU per Hour (BTU/h)
BTU per hour (BTU/h or BTUH) measures heating and cooling capacity. Air conditioners are rated in BTU/h (window unit: 5,000-12,000 BTU/h, central AC: 24,000-60,000 BTU/h). Furnaces range from 40,000-200,000 BTU/h. One BTU/h equals 0.293 watts.
Milliwatt (mW)
A milliwatt (mW) equals 0.001 watts or one-thousandth of a watt. Milliwatts measure laser pointer power (1-5 mW), wireless signal strength (WiFi: 30-100 mW), LED indicator lights, and low-power electronics. Bluetooth devices typically transmit at 1-100 mW.
