Definition of capacity, how many capacity units are there?

Capacity often refers to the size of the volume of an object, and the metric unit of capacity is liters. Capacity also refers to the number of units of objects that can be accommodated in an object or space. Now it is widely used in the measurement of computer hard disks, batteries and other reserves.

Volume: Refers to the volume of the object that the container can hold.

Unit: The volume unit of solids and gases is the same as the volume unit, while the volume unit of liquid is generally liters and milliliters.

Volume and volume are two different concepts, and they are different:

1. The meaning is different. For example, the volume of an iron bucket refers to the size of the part of the space it occupies, while the volume of the bucket refers to the amount of objects it holds. An object has volume, but it does not necessarily have volume.

2. The measurement method is different. Before calculating the volume or volume of an object, it is generally necessary to measure the length, width, and height, and the volume of an object is measured from the outside of the object, while the volume is measured from the inside of the object. An object that has both volume and volume, its volume must be greater than its volume.

3. The name of the unit is not exactly the same. Volume units are generally used: cubic meters, cubic decimeters, cubic centimeters; The volume unit of solids and gases is the same as the volume unit, while the volume unit of liquid is generally liters and milliliters.

Commonly used units of volume are expressed in letters as:

Cubic meters: m3, cubic decimeter dm3, cubic centimeter cm3, cubic millimeter mm3, liter l, milliliter ml, liter and milliliter are mostly used for liquid volume.

The SI system of units for volume is cubic meters m3, and the unit conversion is: 1m3 = 1000dm3, 1dm3 = 1l = 1000cm3 = 1000ml.

Capacitance unit of capacitance:

The unit of capacitance capacity is "farad", which is denoted by the letter "f". Units smaller than f are MF (millifara), f, (microfar), nf (nanofar), and pf (picofara).

The conversion relationship between them is:

1f=1000mf

1mf=1000μf

1μf=1000nf

1nf=1000pf

Due to the capacitance f"The capacity of the unit is very large, so what we see is generally the unit of f, nf, pf. In the common circuit diagram, F, PF some omitted F to display, P actual capacitance annotation method is generally less than 9900P, with P is more than Contained.

Answer: The unit of capacity, i.e., volume, cannot be accurately estimated.

Commonly used units of volume are:cubic meters, cubic decimeters, cubic centimeters, etc.

Volume is generally calculated in volumetric units, such as liters and milliliters, but is sometimes used in conjunction with volume units. When calculating the volume of a larger object, the common unit of volume is "cubic meter". Liters and milliliters are not used to calculate the volume of an object, it is limited to calculating liquids such as potions, gasoline, ink, etc.

【Small Popular Science】Capacity:It often refers to the size of the volume of an object, and the metric unit of capacity is liters. Capacity also refers to the number of units of objects that can be accommodated in an object or space.

Now it is widely used in the measurement of computer hard disks, batteries and other reserves.

Capacity: The size of the volume of an object.

The size of a space surrounded by objects, and the number of cubic units contained in it is called volume; Capacity is the number of units a space contains.

Volume refers to the volume of objects that can be accommodated in boxes, oil drums, warehouses, etc., usually called their volume, measurement volume, and generally used in volume units. When the space occupied by an object is three-dimensional, the size of the space occupied is called the volume of the object. Measuring the volume of liquids, such as water, oil, etc., is commonly used in volume units liters and milliliters, which can also be written as l and ml.

Volume is a geometric term, and when the space occupied by an object is three-dimensional, the size of the space occupied is called the volume of the object. The SI system of units for volume is cubic meters. One-dimensional objects (e.g., lines) and two-dimensional objects (e.g., squares) are zero-volume.

Volume is the volume that a container can hold an object.

Capacity refers to the number of objects that a container can hold.

So the difference between them is that volume emphasizes volume, while capacity is metered.

1. Battery capacity.

is the capacity of the battery of the power bank, measured in ampere-hours (ah) or milliampere-hours (mAh). 10000 mAh.

The reserve of the polymer cell capacity refers to the polymer battery of the power bank.

Length*Width*Thickness*Energy coefficient 10000;

2. The rated capacity is the output capacity of the mobile power supply determined by the manufacturer's trademark, which is expressed by C in ampere-hours (AH) or milliampere-hours (mAh). The rated capacity is the minimum guaranteed capacity that the power bank tested by Wang Burning Slag can output under laboratory conditions under the current of 2A or 1A, and the higher the rated capacity under normal circumstances, the higher the effective energy of the power bank;

Bytes

Definition. Inside a computer, information is stored, calculated, processed, and transmitted in binary form. There are several types of information storage units, such as bits, bytes, and words. There are several storage capacity units of various storage devices, such as KB, MB, GB, and TB. [2]

Basic storage unit.

Bit: A bit in a binary number, which can be 0 or 1, and is the smallest unit of data in a computer.

Byte (b): The basic unit of data in a computer, which consists of a byte for every 8 bits. All kinds of information need at least one byte to store and process in a computer. For example, an ASCII code is represented by one byte, and a Chinese character is represented by two bytes.

Word: Two bytes are called a word. The storage unit of Chinese characters is a single character.

Extended storage units.

In the storage capacity representation of various computer storage media (such as memory, hard disks, optical discs, etc.), the storage units that users are exposed to are not bits, bytes, and words, but kb, MB, GB, etc., but this is not a new storage unit, but is based on byte conversion.

In the early days, floppy disks were 360kb and 720kb, but floppy disks are rarely used anymore.

In the early days, microcomputers had 128MB, 256MB, and 512MB of memory, and now the memory is 1GB, 2GB, or even larger.

In the early days, microcomputers had 60GB and 80GB hard drives, and now they are all 500GB, 1TB or even larger.

The storage capacity of the previous personal use of the microcomputer can also reach this level, and as a server or a specialized computer, such a large storage capacity is indispensable.
