What are the basic metric 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)
Is ampere A metric unit?
The ampere is the SI base unit for electric current in the metric system. An ampere is sometimes also referred to as an amp. Amperes can be abbreviated as A; for example, 1 ampere can be written as 1 A.
What are the three basic units?
In the International System of Units, the fundamental units are:
- The meter (symbol: m), used to measure length.
- The kilogram (symbol: kg), used to measure mass.
- The second (symbol: s), used to measure time.
- The ampere (symbol: A), used to measure electric current.
- The kelvin (symbol: K), used to measure temperature.
What are 5 standard metric units?
So, the units for length, weight (mass) and capacity(volume) in the metric system are: Length: Millimeter (mm), Decimeter (dm), Centimeter (cm), Meter (m), and Kilometer (km) are used to measure how long or wide or tall an object is.
What is the SI unit of input?
In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second.
What is dimensional formula of viscosity?
Viscosity = Force × [Area × Velocity]-1 × Distance between layers. Or, η = [M1 L1 T-2] × [M0 L2 T0]-1 × [M0 L1 T-1]-1 × [M0 L1 T0] = [M1 L-1 T-1]. Therefore, viscosity is dimensionally represented as [M1 L-1 T-1].
What is SI unit of viscosity?
Dynamic viscosity: The SI physical unit of dynamic viscosity (μ) is the Pascal-second (Pa s), which is identical to 1 kg m−1 s−1. The physical unit for dynamic viscosity in the centimeter gram second system of units (cgs) is the poise (P), named after Jean Poiseuille. Kinematic viscosity has SI units of m2 s−1.
