The SI (metric) unit of time is the second.
The second is technically defined thus:
The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.
The cesium atom must be at rest at 0o K (absolute zero temperature).

What are the base units in the SI chart?
SI is based on 'centimetre-gram-second'
What is standard SI unit?
An SI unit is a unit of measure from the International System of Units. SI is the abbreviation for the French Système international d'unités
Is time and temperature examples of basic SI or metric units?
Time and temperature are quantities to be measured. The SI units for time and temperature are the second and the kelvin, respectively.
Is second part of the metric system?
Yes, the second is the unit of time. It is one of the SI base units.
What is momentum and state its SI unit?
Momentum is mass * velocity. Its units, in the SI system are kilogram metre per second
SI units for time length speed and velocity?
SI units: time:second length: meter speed:meter/second velocity:meter/second.
How is time calculated in SI units?
The SI unit for time is the second (s).
What are the base units in the SI chart?
SI is based on 'centimetre-gram-second'
What are the SI units for distance and time?
meter and second
Is a second a si based unit?
Not really. The second is one of the SI system's seven BASE (not 'basic') units.
What is the SI unit for velocity?
Meter per secondThere is no standard SI unit for velocity actually. It is a derived unit. Velocity is distance traveled per time together with the direction of motion. The SI unit of distance is the meter (m) and the SI unit of time is the second (s).So the units of velocity in SI units is meters/second (m/s), or ms-1See the Related Questions link to the left "What are all the SI units" for more information about SI units.CommentDerived units are SI units.
What is the basic unit of time in SI Units?
It's the "second".
What the si units for frequency?
The SI unit for frequency is Hertz, the number of cycles per second.
What is standard SI unit?
An SI unit is a unit of measure from the International System of Units. SI is the abbreviation for the French Système international d'unités
What is the SI units of measure?
The SI has seven base units (kilogram, meter, second, ampere, kelvin, mole, candela), and lots of derived units - for example, meter/second for speed/velocity, coulomb = ampere x second for electrical charge, etc.
What are the fundamental and derived units?
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
What is the relationship between SI and CGS units of force?
SI is the Systeme Internalionale of measurement in which the Metre, kilogram and Second are some primary units. An older system based on metric units used centimetre, gram, and second as the primary units. Obviously these may be converted into SI units, but the CGS system is no longer used. [Some of the definitions of the fundamental units differ between these systems.]
