When we say that, for example, 0.55″ of rain has fallen, we mean a blanket of water exactly 0.55″ in depth would cover all horizontal surfaces if none of the rainwater had soaked in, run off or ...
Pressure is the amount of force applied per unit area. Pressure can be measured by a pressure gauge, but it is important to know the type of pressure the gauge is reading. This article will cover the ...

How to Measure Nothing Better

Cold atoms could also potentially measure much lower vacuum pressures than ion gauges can. The current lowest pressure they’ve reliably measured is around 10 -9 Pa, and NIST scientists are working on ...
A new way of measuring sea level using satellite navigation system signals, for instance GPS, has been implemented by scientists at Chalmers University of Technology in Sweden. Sea level and its ...
St. Martin Parish now has an electronic gauge in Bayou Milhomme near Stephensville. The gauge was installed by USGS (United States Geodetic Survey) and has the ability to measure real-time water ...
A new way of measuring sea level using satellite navigation system signals, for instance GPS, has been implemented. Sea level and its variation can easily be monitored using existing coastal GPS ...
