# What is the CGS and SI unit of length?

## What is the CGS and SI unit of length?

The C.G.S system of units uses the fundamental unit of length as centimetre (cm). Additional information: As different units of measurement, a standard universal unit was needed for convenience. The Standard International (S.I) unit of measurement of length is metre (m).

What is the CGS unit of length?

The centimetre–gram–second system of units (abbreviated CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.

What is the SI unit for length?

meter
The meter, symbol m, is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m s-1, where the second is defined in terms of ΔνCs.

### What is the unit of SI and CGS?

description cgs SI (mks)
electric charge franklin coulomb
electric current biot ampere
electric dipole moment debye coulomb metre
energy (work) erg joule

How do you convert CGS to SI units?

To convert a cgs formula to SI, multiply the symbols by a corresponding factor in Table 1. The derivative quantities are obvious. E.g., volume is r3, therefore is multiplied by 106. The charge density is Q/r3 and is multiplied by 10c/106 = 10−5c, etc.

How do you calculate CGS unit?

1. Unit of velocity in CGS system is cm/s and that in SI system is m/s. 1m/s=100cm/s.
2. SI unit of acceleration=m/s2. CGS unit of acceleration=cm/s2. 1m/s2=100cm/s2.
3. SI unit of momentum=kgm/s.

#### What does CGS stand for?

Centimeter-Gram-Second system
(Centimeter-Gram-Second system) A metric system of measurement that uses the centimeter, gram and second for length, mass and time.

What are the 7 SI base units?

The seven SI base units, which are comprised of:

• Length – meter (m)
• Time – second (s)
• Amount of substance – mole (mole)
• Electric current – ampere (A)
• Temperature – kelvin (K)
• Luminous intensity – candela (cd)
• Mass – kilogram (kg)

What is the SI unit of length class6?

metre (m)
The SI unit of length is metre (m).

## What is CGS full form?

The full form of four systemss of units used in measurements are. CGS system – Centimeter Gram Second system. In the CGS system, fundamental units are Centimeter, Gram and second. MKS system – Meter kilogram second system.

How do you convert CGS to SI?

To convert an SI formula to cgs: Change ε0 to 1/(4π×10−3c2) and µ0 to 4π×10−7. The “strange” factor 4π × 10−3c2 is just 4π × 10−7c2 in SI system.

What is the relation between SI and CGS unit of work?

Therefore, 1 joule = 107 erg. So S.I unit of work = 107 times the C.G.S unit of the work. So this is the required relation between the S.I and the C.G.S unit of the work.
