Many Yemenis in the country's south and east oppose what they see as a Houthi coup, and measuring the depth of their support in areas controlled by the Houthis is difficult.

Which means the makeup functions as a double whammy, preventing infrared lasers from accurately measuring the depth of markers on my face, and the camera can't use its algorithms to make an approximate depth map of my face because the makeup severely flattens things out.

So after measuring the depth of the fuel in the tank in centimeters and successfully converting that to liters, everyone then used a specific gravity of 1.77 to do the conversion: This is the number of pounds per liter for the fuel at that temperature.

Star Trek: Bridge Crew, sampled on this occasion via Oculus Rift, is the best multiplayer virtual reality experience I've had so far—not that I have a great deal to go on, admittedly, both in terms of alternatives played and measuring the depth of the (full) game in question.

On a view camera, the focus and f-number can be obtained by measuring the depth of field and performing simple calculations. Some view cameras include DOF calculators that indicate focus and f-number without the need for any calculations by the photographer.

A Rockwell hardness tester The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load).E.L. Tobolski & A. Fee, "Macroindentation Hardness Testing," ASM Handbook, Volume 8: Mechanical Testing and Evaluation, ASM International, 2000, pp. 203–211, .

A fathom is a unit of length in the imperial and the U.S. customary systems equal to , used especially for measuring the depth of water. The fathom is not an International Standard (SI) unit, nor is it accepted internationally as a non-SI unit. However it is historically the most frequently employed maritime measure of depth in the English speaking world. There are two yards (6 feet) in an imperial fathom.

Lead and line sounding A sounding line or lead line is a length of thin rope with a plummet, generally of lead, at its end. Regardless of the actual composition of the plummet, it is still called a "lead". Leads were swung, or cast, by a leadsman, usually standing in the chains of a ship, up against the shrouds. Measuring the depth of water by lead and line dates back to ancient civilization.

In Journey to the West, the monkey king Sun Wukong obtained his Ruyi Jingu Bang, a magically-expanding, gold-ringed iron rod weapon, from Ao Guang. This weapon was originally a tool for measuring the depth of sea water used by Yu the Great in his flood control and treatment efforts; hence its ability to vary its shape and length. After Yu left, it remained in the sea and became the "Pillar holding down the sea", an unmovable treasure of the undersea palace of Ao Guang. One of Wukong's senior advisors had told him to seek out the dragon-king in order to get a powerful weapon befitting his skill.

Alexander Behm (11 November 1880, in Sternberg (Mecklenburg) – 22 January 1952, in Tarp (Schleswig-Flensburg)) was a German physicist who developed working ocean echo sounder in Germany at the same time Reginald Fessenden was doing so in North America. As head of a research laboratory in Vienna (Austria) he conducted experiments concerning the propagation of sound. He tried to develop an iceberg detection system using reflected sound waves after the Titanic disaster on 15 April 1912. In the end reflected sound waves proved not to be suitable for the detection of icebergs but for measuring the depth of the sea, because the bottom of the sea reflected them well.

Hydrolevelling is an alternative to measuring depth with clinometer and tape that has a long history of use in Russia. The technique is regularly used in building construction for finding two points with the same height, as in levelling a floor. In the simplest case, a tube with both ends open is used, attached to a strip of wood, and the tube is filled with water and the depth at each end marked. In Russia, measuring the depth of caves by hydrolevelling began in the 1970s, and was considered to be the most accurate means of measuring depth despite the difficulties in using the cumbersome equipment of the time.

The sea-ice observations will cover the broad range from the physical and mechanical characteristics of Arctic sea ice, to its morphology, optical properties and mass balance. The emphasis will be on characterising snow cover and ice cover, and on arriving at a better understanding of the processes that determine their properties. Snow trenches and ice cores will help the researchers gather this valuable data. Further aspects of the sea ice observation will include determining the mass budget by measuring the depth of snow cover and ice thickness, as well as measuring the diffusion of sunlight in the ice, the ice's spectral albedo, and its transmission.

One can get by without referring to charts, but they are an important tool and a part of good anchoring gear, and a skilled mariner would not choose to anchor without them. The depth of water is necessary for determining scope, which is the ratio of length of cable to the depth measured from the highest point (usually the anchor roller or bow chock) to the seabed. For example, if the water is deep, and the anchor roller is above the water, the scope is the ratio between the amount of cable let out and . For this reason it is important to have a reliable and accurate method of measuring the depth of water.

Bathymetry is the mapping and study of the topography of the ocean floor. Methods used for measuring the depth of the sea include single or multibeam echosounders, laser airborne depth sounders and the calculation of depths from satellite remote sensing data. This information is used for determining the routes of undersea cables and pipelines, for choosing suitable locations for siting oil rigs and offshore wind turbines and for identifying possible new fisheries. Ongoing oceanographic research includes marine lifeforms, conservation, the marine environment, the chemistry of the ocean, the studying and modelling of climate dynamics, the air-sea boundary, weather patterns, ocean resources, renewable energy, waves and currents, and the design and development of new tools and technologies for investigating the deep.

Chamber pressure gauge calibrated in msw and bar The commonly used units of pressure for hyperbaric treatment are metres of sea water (msw) and feet of sea water (fsw) which indicate the pressure of treatment in terms of the height of water column that would be supported in a manometer. These units are also used for measuring the depth of a surface supplied diver using a and directly relate the pressure to an equivalent depth. The pressure gauges used on diving chambers are often calibrated in both of these units. Elapsed time of treatment is usually recorded in minutes, or hours and minutes, and may be measured from the start of pressurisation, or from the time when treatment pressure is reached.

Nested well and well cluster (adapted from Johnson [1983]) Nested wells, also referred to as nested monitoring wells, are composed of multiple tubes or pipes, typically terminating with short screened intervals (2–3 ft), installed in single boreholes. Sand packs must be installed at the screen depths and seals in the borehole are constructed between the sand packs. Nested wells are different from well clusters in that the latter consists of a cluster of wells where tubes or pipes are constructed in separate, individual boreholes that are drilled and completed at different depths. When constructing nested wells, attention must be paid to ensure the proper placement of sand in the screened intervals and bentonite between monitored intervals, by measuring the depth of the sand or bentonite frequently as the materials are being placed.

In the early days of the Joseon Dynasty, there was a system to measure and report a region's rainfall for the sake of agriculture. However, the method to measure rainfall in those days was primitive, measuring the depth of rain water in puddles. This method could not tell the exact rainfall, because there are differences in the amount of rainwater absorbed into the ground by the nature of the local soil. To prevent errors of this kind, King Sejong the Great ordered the Gwansanggam (Hangul:관상감, Hanja:觀象監) (the Joseon kingdom's research institute of astronomy, geography, calendar and weather) to build a rainwater container, the Cheugugi, made of iron in August 1441 (according to the lunar calendar) based on the idea of his Crown Prince, later became Munjong of Joseon.
