- [Torque conversion chart](https://konvertera.nu/school/unit-tables/torque/): The torque conversion chart: kilonewton metres down to millinewton metres, plus the kilopond metre. Edit, print and share.
- [Force conversion chart](https://konvertera.nu/school/unit-tables/force/): The force conversion chart: meganewtons down to millinewtons, plus the kilopond and the tonne-force. Edit, print and share.
- [Watt (W)](https://konvertera.nu/international-system-of-units/watt/): Power states how fast energy is converted: how much work is done or heat given off per unit of time. We meet it daily on lamps, electricity bills, engines and power stations. In the International System of Units (SI), power is measured in watts, symbol W. The watt is a derived SI unit, defined entirely through the base units kilogram, metre and second, with no definition of its own beside them.
- [Volt (V)](https://konvertera.nu/international-system-of-units/volt/): Electric potential difference, or voltage, is the quantity that drives current through a circuit and states how much energy each unit of charge carries. The volt, symbol V, is the SI unit of voltage and one of the most widely used derived SI units. It appears everywhere from batteries and wall sockets to power lines and nerve signals, yet few people know how it is defined and how it is realized in a measurement laboratory.
- [Pascal (Pa)](https://konvertera.nu/international-system-of-units/pascal/): Pressure is found everywhere: in the atmosphere, in liquids, in tyres, in pipelines and in the bloodstream. Yet everyday pressure is stated in a motley collection of units, from bar and atmosphere to millimetres of mercury and psi. The International System of Units (SI) has only one unit of pressure: the pascal, symbol Pa. The pascal is a derived SI unit, built from the base units kilogram, metre and second with no definition of its own beside them.
- [Ohm (Ω)](https://konvertera.nu/international-system-of-units/ohm/): Electrical resistance states how strongly a conductor opposes the current flowing through it. The ohm, symbol Ω (the Greek letter omega), is the SI unit of resistance and a derived SI unit. It is fundamental to all electrical engineering, from the sizing of cables to the design of electronic circuits, yet its modern definition and realization are less well known.
- [Newton (N)](https://konvertera.nu/international-system-of-units/newton/): Force is the quantity that describes how objects act on one another: a force changes an object's velocity, deforms it or holds it in place against other forces. The newton, symbol N, is the SI unit of force and one of the most widely used derived SI units. Unlike the kilogram, the meter and the second, the newton is not a base unit; it is built from them.
- [Joule (J)](https://konvertera.nu/international-system-of-units/joule/): Energy unites mechanics, thermodynamics, electricity and chemistry: one unit describes the work of a crane, the heat in a saucepan and the energy content of a food. The joule, symbol J, is the SI unit of energy, work and heat, and one of the most central derived SI units. It is built from the base units kilogram, meter and second.
- [Hertz (Hz)](https://konvertera.nu/international-system-of-units/hertz/): Frequency states how many times a periodic process repeats per unit of time. The quantity runs through acoustics, radio engineering, power systems and computing, and its SI unit, the hertz (Hz), is one of the derived SI units. The unit is named after the German physicist Heinrich Hertz (1857-1894), who demonstrated electromagnetic waves experimentally.
- [Farad (F)](https://konvertera.nu/international-system-of-units/farad/): Capacitance is a measure of how much electric charge a component can store per volt of applied voltage. The quantity is central to electronics, power engineering and measurement, and its SI unit, the farad (F), is one of the derived SI units. The unit is named after the English physicist and chemist Michael Faraday (1791-1867).

- [Candela (cd)](https://konvertera.nu/international-system-of-units/candela/): Luminous intensity is a fundamental quantity in photometry and lighting technology and describes how strong a light source appears to the human eye in a given direction. Unlike several other physical quantities, the candela is not tied solely to objectively measurable energy flows, but also takes human vision into account.
- [Mole (mol)](https://konvertera.nu/international-system-of-units/mole/): Amount of substance is a fundamental quantity in chemistry, physics and materials science. It counts how many elementary entities (such as atoms, molecules, ions or other particles) a system contains. The SI unit of amount of substance is the mole. Despite its central role in the sciences, how the mole is actually defined, and how that definition relates to mass and the number of particles, is often unclear.
- [Ampere (A)](https://konvertera.nu/international-system-of-units/ampere/): Electric current is a fundamental quantity in physics, engineering and modern infrastructure. Energy distribution, electronics, communication and measurement technology all rely on precise control of electric current. Its present definition, and how that definition is realized, is less familiar.
- [Second (s)](https://konvertera.nu/international-system-of-units/second/): Time underlies much of science and engineering. Motion, energy, frequency and speed can all be described in terms of time. Its present definition, and how that definition is realized in practice, is less familiar than the quantity itself.
- [Kelvin (K)](https://konvertera.nu/international-system-of-units/kelvin/): Temperature is a fundamental physical quantity that describes the thermal state of a system. It affects chemical reactions, material properties, biological processes and technical systems. The modern definition of the kelvin, and how it is realized, is less well known.
- [Kilogram (kg)](https://konvertera.nu/international-system-of-units/kilogram/): Mass is one of the most fundamental quantities in physics, engineering and chemistry. Its modern definition, and how that definition becomes a practical measurement, is less familiar. For most of its history the kilogram was tied to a physical object. It is now defined through a fundamental constant of nature.
- [Meter (m)](https://konvertera.nu/international-system-of-units/meter/): Length is a fundamental physical quantity used throughout science, engineering and everyday measurement. How the meter is defined today is not widely known outside metrology. The meter is no longer tied to a physical reference object; it is defined using fundamental constants of nature.
