Mass Conversion

Equals

Important Notes
  • The standard International System of Units (SI) unit of mass is the kilogram (kg). The kilogram is 1000 grams (g) and the tonne (t) (or "metric ton") is equal to 1000 kg.
  • The pound (lb) is a unit of both mass and force, used mainly in the United States (about 0.45 kg or 4.5 N). In scientific contexts where pound (force) and pound (mass) need to be distinguished, SI units are usually used instead.
  • The slug (sl) is an Imperial unit of mass of 32.1740 lb (about 14.6 kg) based on standard gravity.
  • The electronvolt (eV) is a unit of energy, but because of the mass–energy equivalence it can easily be converted to a unit of mass and is often used like one. In this context, the mass has units of eV/c2 (where c is the speed of light). The electronvolt and its multiples, such as the MeV (megaelectronvolt), are commonly used in particle physics.
  • The atomic mass unit (u) is 1/12 of the mass of a carbon-12 atom, approximately 1.66×10−27 kg. The atomic mass unit is convenient for expressing the masses of atoms and molecules.

Mass

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.
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. An object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force while mass is the property that (along with gravity) determines the strength of this force.

Angle
Angle Converter

In plane geometry, an Angle (Latin word angulus, meaning "corner") is the figure formed by two rays called the sides of the angle, sharing a common endpoint called the vertex of the angle. Angle is also used to designate the measure of an angle or of a rotation. This measure is the ratio of the length of a circular arc to its . . . .

Pressure
Pressure Converter

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, Gauge Pressure etc. Atmospheric . . . .

Speed
Speed Converter

In everyday use and in kinematics, the Speed of an object is the magnitude of the change of its position. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval, whereas the instantaneous speed is the limit of the average speed as the duration of the . . . .

Volume
Volume Converter & Calculator

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic meter. The volume of a container is generally understood . . . .

History of Measurement :

The earliest recorded systems of calculations and measures originate in the 3rd or 4th millennium BC. Even the very earliest civilizations needed measurement for purposes of agriculture, construction and trade. Early standard units might only have applied to a single community or small region, with every area developing its own standards for lengths, areas, volumes and masses.

With the development of manufacturing technologies and the growing importance of trade between communities and ultimately across the Earth, standardized weights and measures became critical. Starting in the 18th century, modernized, simplified and uniform systems of weights and measures were developed, with the fundamental units defined by ever more precise methods in the science of metrology.
