In US use, the grade designation is equal to the minimum yield strength of the bar in ksi (1000 psi); for example, grade 60 rebar has a minimum yield strength of 60 ksi. Rebar is most commonly manufactured in grades 40, 60, and 75 with higher strength readily available in grades 80, 100, 120 and 150.
Volume was measured in ngogn (equal to 1000 cubic potrzebies), mass in blintz (equal to the mass of 1 ngogn of halva, which is "a form of pie [with] a specific gravity of 3.1416 and a specific heat of .31416"), and time in seven named units (decimal powers of the average earth rotation, equal to 1 "clarke").
The Great Pyramid of Giza [a] is the largest Egyptian pyramid.It served as the tomb of pharaoh Khufu, who ruled during the Fourth Dynasty of the Old Kingdom.Built c. 2600 BC, [3] over a period of about 26 years, [4] the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact.

The solar constant is equal to approximately 1,368 W/m 2 (watts per square meter) at a distance of one astronomical unit (AU) from the Sun (that is, at or near Earth's orbit). [99] Sunlight on the surface of Earth is attenuated by Earth's atmosphere , so that less power arrives at the surface (closer to 1,000 W/m 2 ) in clear conditions when ...
The average shoulder height for males of the species has been estimated at 2.8–3.15 m (9 ft 2 in – 10 ft 4 in) with a weight of 4.5–6 t (9,900–13,200 lb), with females being smaller like living elephants, with a shoulder height of 2.3–2.6 m (7 ft 7 in – 8 ft 6 in) and a weight of 2.8–4 t (6,200–8,800 lb).

At 1 atm pressure, it reaches its maximum density of 999.972 kg/m 3 (62.4262 lb/cu ft) at 3.98 °C (39.16 °F). [ 54 ] [ 55 ] Below that temperature, but above the freezing point of 0 °C (32 °F), it expands becoming less dense until it reaches freezing point, reaching a density in its liquid phase of 999.8 kg/m 3 (62.4155 lb/cu ft).
