10.16 cm = 1.016 dm — 1 hand used in measuring height of horses (4 inches) 12 cm = 1.2 dm — diameter of a Compact Disc (CD) (= 120 mm) 15 cm = 1.5 dm — length of a Bic pen with cap on; 22 cm = 2.2 dm — diameter of a typical soccer ball; 30.48 cm = 3.048 dm — 1 foot; 30 cm = 3 dm — typical school-use ruler length (= 300 mm)
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
The giraffe's circulatory system has several adaptations to compensate for its great height. [16] Its 11 kg (25 lb) and 60 cm (2 ft) heart must generate approximately double the blood pressure required for a human to maintain blood flow to the brain. As such, the wall of the heart can be as thick as 7.5 cm (3.0 in). [52]
The number of cases was 57,574, with an average age of 48 years and a median age of 47 years. They were all over 18 years old at the time of the investigation. Regardless of age, urbanity or rurality, ethnic groups, or provinces, the average height of males was 169.60 cm, while the average height of females was 158.88 cm.
The S-II was 81.6 feet (24.87 m) tall with a diameter of 33 feet (10 m), identical to the S-IC, [61] [62] and thus was the largest cryogenic stage until the launch of the Space Shuttle in 1981. The S-II had a dry mass of about 80,000 pounds (36,000 kg); when fully fueled, it weighed 1,060,000 pounds (480,000 kg).
It has a density of up to 150 g/cm 3 [60] [61] (about 150 times the density of water) and a temperature of close to 15.7 million kelvin (K). [61] By contrast, the Sun's surface temperature is about 5800 K. Recent analysis of SOHO mission data favors the idea that the core is rotating faster than the radiative zone outside it. [59]
The first molars were about the size of those of a human, 1.3 cm (0.51 in), the third were 15 cm (5.9 in) long, and the sixth were about 30 cm (12 in) long and weighed 1.8 kg (4.0 lb). The molars grew larger and contained more ridges with each replacement. [ 57 ]
According to the Guinness World Records, the tallest human in recorded history was Robert Wadlow of the United States (1918–1940), who was 272 cm (8 ft 11 in). He received media attention in 1939 when he was measured to be the tallest man in the world, After reaching a height of 267 cm (8 ft 9 in). There are reports about even taller people ...
