Physics All Length Conversion Concept Formula

The conversion relationship between them is as follows: 1km=103m: 1m=10dm=102cm=103mm=106 m=109nm; 1mm=10-3m；1μm=10-6m；1nm=10-9m。

In the International System of Units, the basic unit of length is the meter (m), the unit of length larger than the "meter" is the "kilometer (km)", and the length unit smaller than the "meter" is "decimeter (dm)", "centimeter (cm)", millimeter (mm), micron (m), nanometer (nm), etc.

The conversion of the physical units in the first volume of the eighth grade is as follows:

Kilometer is equal to 1000 meters, 1 meter is equal to 10 decimeters, 1 decimeter is equal to 10 centimeters, 1 centimeter is equal to 10 millimeters, 1 millimeter is equal to 1000 microns, and 1 micron is equal to 1000 nanometers;

A milliliter is equal to 1 cubic centimeter, 1 cubic decimeter is equal to 1000 cubic centimeters, and 1 cubic meter is equal to 1000 cubic decimeters;

Hour is equal to 60 minutes, 1 minute is equal to 60 seconds, and 1 meter per second is equal to kilometers per hour;

Tons are equal to 1000 kilograms, 1 kilogram is equal to 1000 grams, and 1 gram is equal to 1000 milligrams;

A square meter is equal to 100 square decimeters, and 1 square decimeter is equal to 100 square centimeters.

Note: In the International System of Units, the basic unit of length is the meter (m), the length unit larger than the "meter" is "kilometer (km)", and the length unit smaller than the "meter" is "decimeter (dm)", centimeter (cm), millimeter (mm), micron (m), nanometer (nm), etc. Their conversion relationship:

The conversion relationship between them is: 1km=103m; 1m=10dm=102cm=103mm=106μm=109nm；1mm=10-3m；1μm=10-6m；1nm=10-9m。Therefore, as long as you master these conversion relationships, you can do this kind of calculation problem very well.

1 meter = ( ) cm, 1 cm = ( ) mm.

9000 m = ( ) km 1 km = ( ) m.

3 m = ( ) decimeter 20 dm = ( ) m.

2 m = ( ) cm.

600 centimeters = ( ) meters.

15 dm = = ( ) m; 510 m = = ( ) km ; 16 cm = = ( ) m ; m = = ( ) cm ; 60 mm = ( ) cm; 8 meters = ( ) decimeters.

m = = ( ) cm ; 50 m = ( ) km.

504 cm = ( ) m; 7 decimeters = ( ) meters.

500 μm = = ( ) cm; 50 mm = = ( ) nm.

160 mm = = ( ) m.

It is actually relatively easy to convert the unit of length, as long as you remember the meaning of a few common letters, such as: k (thousand) m (milli).

Micro) n( nano) 1 k=10 3 1 m=10 (-3) 1 =10 (-6) 1 n =10 (-9).

Then use the mathematical equation to establish a relationship conversion, there is no need to memorize.

For example, km = 10 3 m (just replace k with 10 3), m = 10 (-3 ) km (because k means 10 3 has been multiplied, so 10 (-3 ) is used to offset it), and so on.

In addition, about meters (m), decimeters (dm), centimeters (cm), millimeters (mm), you have learned in elementary school, they are all converted in decimal system:

1 m = 10 dm 1 dm = 10 cm 1 cm = 10 mm

Cubic thousand, adjacent units are 1000 times, 1m 3 = 1000dm 3 1dm 3 = 1000cm 3

square decimal system, adjacent units are 100 times. 1m^2=100dm^2 1dm^2=100cm^2

Non-square cube, adjacent units are 10 times, 1m=10dm 1dm=10cm1k represents 1000
