what is the difference between physical units and equivalent units?

Equivalent units. are calculated by multiplying the number of physical (or actual) units on hand by the percentage of completion of the units. If the physical units are 100 percent complete, equivalent units will be the same as the physical units.

What is the difference between a physical model and a conceptual model? A physical model is a representation of a very large or small object shown at a convenient scale. A conceptual model is an explanation that treats what is being explained as a system.

The absolute unit of force in the International System of Units (SI units) is Newton. It is defined as the force necessary to provide a mass of one kilogram with an acceleration of one meter per second per second. Whereas the gravitational unit of force is "kgf" or "kilogram-force" .

The basic SI unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses.

Originally Answered: Metric to standard? ... The main difference is that metric uses powers of 10 only (10 mm in a cm, 100 cm in a meter, 1000 m in a km), while the old units did not (12 inches in 1 foot, 3 feet in a yard, 5280 feet in a mile). Metric also uses the same prefixes for each type of measurements.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity.

11. What's the difference between a milligram (mg), microgram (mcg), and an International Unit (IU)? In the metric system, 1000 milligrams (mg) is a unit of mass equal to 1 gram and 1000 micrograms (mcg) is equal to 1 milligram (mg). ... 1 IU is the biological equivalent of 0.025 mcg cholecalciferol or ergocalciferol.

A base unit (also referred to as a fundamental unit) is a unit adopted for measurement of a base quantity. A base quantity is one of a conventionally chosen subset of physical quantities, where no quantity in the subset can be expressed in terms of the others.

Standard units are dimensionless. If the original list has units, the original SD has the same units. To transform a measurement to standard units, we divide the measurement (minus the mean) by the SD, which cancels the original units.

MKS System of Measurements: It is a metric system. The main difference between the SI and MKS units is that while the definition of SI units is maintained by a governing body, the definitions in the MKS system vary over time and from place to place.

The specific heat of a substance (per unit of mass) has dimension L2·Θ−1·T−2, or (L/T)2/Θ. Therefore, the SI unit J/K/kg is equivalent to metre squared per second squared per kelvin (m2 K−1 s−2).
