Convert time units, hours, minutes, seconds, days, weeks, months
There are different calendars used worldwide but international standard is gregorian calendar.
Second is the SI base unit of time and officially defined as 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 caesium 133 atom.
This time conversion calculator converts the most common time units, second, hour, minute, day, week, month, year, century and more.
Convert metric and imperial length, distance units
Length (distance) is one dimensional measure between two end points.
There are many units used for length measurement. In metric system, basic unit of length is meter (m) and defined as speed of light. Other metric length units kilometer (km), centimeter (cm), millimeter (mm) are widely used.
In imperial system, common length units are foot, inch, yard and mile.
The purpose of this document is to provide information, formulas and documentation to take certain electrical values and convert them into other electrical values. The formulas below are known and used universally but we use them here in association with computer, network, telecom and other IT equipment.
Density conversion is a free online calculator for converting metric and imperial units of density. Conversion between kilogram/cubic meter, gram/cubic centimeter, kilogram/liter, pound/cubic inch, gram/cubic centimeter
Convert energy units, joules, calories, btu, erg, kwh, mwh
Energy is a measure of how long we can sustain the output of power, or how much work we can do. There are two kinds of energy: potential and kinetic.
Potential energy is waiting to be converted into power. Gasoline in a fuel tank as an example. Kinetic energy is energy a body possesses because it is in motion.
Work is the application of a force over a distance. Work is equal to the product of the force and the distance through which it produces movement.
Convert speed units, meters per second, miles per hour, kilometers per hour
Speed is defined as the rate of change in position, expressed as distance traveled per unit of time. Speed is a scalar quantity with dimensions distance/time. Velocity is a vector quantity, the rate at which an object changes it's position.
In order to calculate speed, the formula is :
Speed = Distance / Time
Speed unit in SI system is meters per second (mps).
Other speed units such as miles per hour (mph), kilometers per hour (kph) are also widely used.
Convert mpg (miles per gallon), liters per 100 kilometers (km) and more
Fuel consumption is the amount of fuel used for a unit of distance. Gallons, liters per 100 kilometers (liter/100 km), gallons per 100 miles are normally used in europe to compare fuel consumption. The lower the value, the car, the vehicle has better gas mileage.
Fuel economy, efficiency is the distance traveled per unit of fuel, gas. Kilometers per liter, miles per gallon (mpg), miles per liter, km per gallons are used in north america, uk, for gas economy. The higher the value, the car is more fuel efficient.
Volume is the amount of three dimensional space occupied by an object. It can be calculated by different formulas depending on the shape of the object.
In metric system, unit of volume is cubic meters. Liter is not a metric unit but widely used in metric system. The most common imperial volume units are gallon, quart, pint.
This conversion calculator converts the most common volume units.
