How many centimeters is an inch and a half?

Question 1: How many centimeters was an inch and a half in ancient times? Different dynasties have different sizes and lengths. The longer the dimension, the longer it is. For example, the length of the ruler is a tiger's mouth (pictographic), about seventeen or eighteen centimeters. In the Han dynasty, one foot was about 23 cm. In the Qing Dynasty, it was one foot long and 35 centimeters. One inch and two cents equals 0. 12 feet. You can calculate the length of each dynasty.

Question 2: How many centimeters is an inch and a half? 1 m =3 feet =30 inches = 100 cm.

1 inch =10/3cm

1.2 inch = (12/10) (10/3) = 4cm.

Question 3: How many centimeters is one inch and two cents, how many centimeters is three inches and six cents, 10 cm = 3 inches, 1 inch = 10 cents, if converted, one inch and two cents =4cm, and three inches and six cents = 12cm.

Question 4: How long is an inch and two minutes? 3 inches = 1 m, 1 inch =33.3 cm.

Question 5: The photos are divided into one inch and two inches. For example, how long and wide is an inch? An inch is 3.6 cm long and 2.5 cm wide. Two inches is 4.8 cm long and 3.3 cm wide.

Question 6: What is the diameter of one-inch pipe? 3.34 cm

1 inch pipe corresponds to DN25, with an outer diameter of 33.4 mm. ..

In order to make the connection size of pipes and fittings consistent, the nominal diameter (also called nominal caliber and nominal diameter) is adopted. For example, welded steel pipes can be divided into thin-walled steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither outer diameter nor inner diameter, but a nominal size similar to the inner diameter of ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and its inner diameter value varies with thickness. Nominal diameter can be expressed in metric millimeters or British inches.

Question 7: What is the outside diameter of inch 2, 33.4mm?
