## 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?**

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