Foot (length) in the context of "Square foot"

A fathom is a unit of length in the imperial and U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water. The fathom is neither an international standard (SI) unit, nor an internationally accepted non-SI unit. Historically, it was the maritime measure of depth in the English-speaking world but, apart from within the US, charts now use metres.

There are two yards (6 feet) in an imperial fathom. Originally the span of a man's outstretched arms, the size of a fathom has varied slightly depending on whether it was defined as a thousandth of an (Admiralty) nautical mile or as a multiple of the imperial yard. Formerly, the term was used for any of several units of length varying around 5–5+1⁄2 feet (1.5–1.7 m).

A cubic yard (symbol yd) is an imperial / U.S. customary (non-SI non-metric) unit of volume used in Canada and the United States. It is defined as the volume of a cube with sides of 1 yard (3 feet, 36 inches, 0.9144 meters) in length.

Tolimán, also known as Volcán Tolimán, is a stratovolcano in Guatemala, on the southern shores of Lake Atitlán. Part of the Sierra Madre mountain range, the volcano has an elevation of 3,158 m (10,361 ft) and was formed near the southern margin of the Pleistocene Atitlán III caldera. The top of the volcano has a shallow crater and its flanks are covered with the thick remains of ancient lava flows that emerged from vents in the volcano's flanks.

Stream gradient (or stream slope) is the grade (or slope) of a stream. It is measured by the ratio of drop in elevation and horizontal distance. It is a dimensionless quantity, usually expressed in units of meters per kilometer (m/km) or feet per mile (ft/mi); it may also be expressed in percent (%).The world average river reach slope is 2.6 m/km or 0.26%;a slope smaller than 1% and greater than 4% is considered gentle and steep, respectively.

Stream gradient may change along the stream course.An average gradient can be defined, known as the relief ratio, which gives the average drop in elevation per unit length of river.The calculation is the difference in elevation between the river's source and the river terminus (confluence or mouth) divided by the total length of the river or stream.

The cubic foot (symbol ft or cu ft) is an imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot (0.3048 m) in length, or exactly 28.316846592 L, which is very close to ⁠1/35⁠ of a cubic metre).

The exposed geology of the Capitol Reef area presents a record of mostly Mesozoic-aged sedimentation in an area of North America in and around Capitol Reef National Park, on the Colorado Plateau in southeastern Utah.

Nearly 10,000 feet (3,000 m) of sedimentary strata are found in the Capitol Reef area, representing nearly 200 million years of geologic history of the south-central part of the U.S. state of Utah. These rocks range in age from Permian (as old as 270 million years old) to Cretaceous (as young as 80 million years old.) Rock layers in the area reveal ancient climates as varied as rivers and swamps (Chinle Formation), Sahara-like deserts (Navajo Sandstone), and shallow ocean (Mancos Shale).
