The cubit was based on the length of the arm from the elbow to the tip of the middle finger and was deemed the equivalent of 6 palms or 2 spans, hence it was used to measure short distances. It was commonly taken as equal to 18 inches (457 mm). 1.3 At sea level, the water boils at 100 ºC (212 ºF). No, because the boiling point of water reduces by around 0.5 ºC for every 150 metres of elevation gain, the boiling point of water in Durban and Johannesburg are not the same. 1.4 They both measure temperature. 1.5 The International System of units (SI), commonly known as the metric system, is the international standard for measurement. 1.6 Sexagesimal is a numeric system with sixty as its basis, commonly known as base to or sexagenary. It was invented by the Sumerians in the third millennium BC, passed down to the Babylonians, and is currently used in a modified form for measuring time, angles, and geographic coordinates. 1.7 100 000 square meter = 1 square kilometre 1.8 1 inch = 2.54 cm 1.9 The entire weight of the tractor and trailer while the vehicle is empty, that is, when there is no product in the trailer, is known as the tare weight. Unladen weight is another term for tare weight. 1.10 It is named after Pope Gregory XIII, was declared in 1582 to correct the gradual inaccuracy that drifted in because of the popularly used calendar of the time. 1.11 A solstice occurs when the Earth's orbit around the sun is at its greatest distance from the equator, while an equinox occurs when it is at its shortest distance. 1.12 A leap year is a year of 366 days, including 29 February as an intercalary year, that occurs every four years. Year 1900 was not a leap year, but year 2000 was a leap year. 1.13 9.99 cm 1.14 Hectare is a metric unit of square metre, equal to 100 Ares (2.471 acres or 10,000 square metres). 1.15 The thermostat is a device that automatically regulates temperature, or that activates a device when the temperature reaches a certain point. 1.16 24 hours × 60 = 1440 minutes 1440 minutes × 60 = 86400 seconds per day
