Current occupants of these rarefied frequencies (also known as "millimetre waves" because of the wavelength) include satellite television, microwave relay links, air-traffic control radar, radio astronomy and amateur radio.In most regions of the world, a chunk of spectrum around 60GHz has been designated for use by the public without a licence.
At sea level and a barometric pressure of 760 millimetres of mercury, the partial pressure of nitrogen is 79.02 percent of 760 millimetres of mercury, or 600.55 millimetres of mercury; that of oxygen is 159.16 millimetres of mercury; and that of carbon dioxide is 0.20 millimetres of mercury.
At 7,600 metres (25,000 feet) the atmospheric pressure is 282 millimetres of mercury and the partial pressure of oxygen is about 59 millimetres of mercury.
With good reason: Leonid Brezhnev, who had given his name to the "Brezhnev doctrine" because of his fondness for sending tanks into countries which stepped a few millimetres out of line, was in power in the Kremlin.
Seconds later Louis Saha was millimetres shy of converting Tony Hibbert's cross.
The independent variables were age (months), sex (male/female), ASA physical status, systolic blood pressure (millimetres of mercury), vein diameter (millimetres), depth of the vein (millimetres), and ultrasound guidance (with/without).
Greenland accounts for 0.6 millimetres of the annual rise in the level of our oceans.
Despite this, there is usually a decrease in a pregnant woman's blood cell count the number of red cells per cubic millimetre of blood because the amount of blood plasma increases approximately 30 percent, while the total number of red blood cells increases by only about 20 percent.
At a scale of millimetres or even millionths of millimetres, the wavelengths of matter are too short to be observed.
It's millimetres of a tail feather.
