Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT}°F = 9 5 {ΔT}°C. To convert a delta temperature from degrees ...
Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. [1] The word technology can also mean the products resulting from such efforts, [2] [3] including both tangible tools such as utensils or machines, and intangible ones such as software.
The spiral balance spring is visible at top. A balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or ...
Thermodynamics. In thermodynamics, a temperature–entropy ( T–s) diagram is a thermodynamic diagram used to visualize changes to temperature ( T ) and specific entropy ( s) during a thermodynamic process or cycle as the graph of a curve. It is a useful and common tool, particularly because it helps to visualize the heat transfer during a ...
English: Video showing most recent ~140 years of global warming in the perspective of the last ~2000 years. Method: I simplified the two source SVG images (below) in Inkscape, exported to big PNG files, and used Photoshop Elements to generate 59 frame-by-frame PNG images for Shotcut to generate the continuous transition this webm video.
IP code. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [ 1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical ...

Historical air monitoring data including AQI charts and maps are available at EPA's AirData website. [53] There is a free email subscription service for New York inhabitants – AirNYC. [54] Subscribers get notifications about the changes in the AQI values for the selected location (e.g. home address), based on air quality conditions.
