    An American football field, including both end zones, is 360 by 160 ft (120.0 by 53.3 yd; 109.7 by 48.8 m), or 57,600 square feet (5,350 m 2) (0.535 hectares or 1.32 acres). A Canadian football field is 65 yards (59 m) wide and 110 yards (100 m) long with end zones adding a combined 40 yards (37 m) to the length, making it 87,750 square feet ...

    en.wikipedia.org/wiki/Speed_of_sound

    For example, while sound travels at 343 m/s in air, it travels at 1481 m/s in water (almost 4.3 times as fast) and at 5120 m/s in iron (almost 15 times as fast). In an exceptionally stiff material such as diamond , sound travels at 12,000 m/s (39,370 ft/s), [ 2 ] – about 35 times its speed in air and about the fastest it can travel under ...

    In addition to coastline lengths, this is the source of the land area used to calculate the "coast/area ratio" for both TWF and WRI (see below) coastline measurement. This ratio measures how many metres of coastline correspond to every square kilometer of land area. The ratio illustrates the ease of accessibility to the country's coast from ...

    en.wikipedia.org/wiki/Dinosaur

    While the dinosaurs' modern-day surviving avian lineage (birds) are generally small due to the constraints of flight, many prehistoric dinosaurs (non-avian and avian) were large-bodied—the largest sauropod dinosaurs are estimated to have reached lengths of 39.7 meters (130 feet) and heights of 18 m (59 ft) and were the largest land animals of ...

  8. Sea level rise - Wikipedia

    en.wikipedia.org/wiki/Sea_level_rise

    With high emissions it would instead accelerate further, and could rise by 1.0 m (3 + 1 ⁄ 3 ft) or even 1.6 m (5 + 1 ⁄ 3 ft) by 2100. [ 5 ] [ 3 ] : 1302 In the long run, sea level rise would amount to 2–3 m (7–10 ft) over the next 2000 years if warming stays to its current 1.5 °C (2.7 °F) over the pre-industrial past.
