Engineering & Science Units Explained

Force Units

Force measures the push or pull on an object. Common units: newton (N), kilonewton (kN), pound-force (lbf).

Pressure Units

Pressure is force per unit area. Common units: pascal (Pa), bar, atmosphere (atm), pounds per square inch (psi).

Energy Units

Energy is the capacity to do work. Common units: joule (J), kilojoule (kJ), calorie (cal), kilowatt-hour (kWh), BTU.

Power Units

Power is the rate of doing work. Common units: watt (W), kilowatt (kW), horsepower (hp).

Torque Units

Torque measures rotational force. Common units: newton-meter (Nm), pound-foot (lb·ft), kilogram-force meter (kgf·m).

Density Units

Density is mass per unit volume. Common units: kilogram per cubic meter (kg/m³), gram per cubic centimeter (g/cm³), pound per cubic foot (lb/ft³).

Specific Volume Units

Specific volume is volume per unit mass. Common units: cubic meter per kilogram (m³/kg), cubic foot per pound (ft³/lb).

Moment of Inertia Units

Moment of inertia measures an object's resistance to rotational acceleration. Common units: kilogram meter² (kg·m²), gram centimeter² (g·cm²), pound foot² (lb·ft²).

Thermal Expansion Units

Thermal expansion measures how much a material expands with temperature. Common units: 1/K, 1/°C, 1/°F.

Heat Capacity Units

Heat capacity is the amount of heat needed to change a substance's temperature. Common units: joule per kelvin (J/K), calorie per kelvin (cal/K), BTU per degree Fahrenheit (BTU/°F).

Electric Resistance Units

Electric resistance measures how much a material opposes electric current. Common units: ohm (Ω), kiloohm (kΩ), megaohm (MΩ).

Electric Conductance Units

Electric conductance is the inverse of resistance. Common units: siemens (S), millisiemens (mS), microsiemens (μS).

Electric Potential Units

Electric potential is the energy per unit charge. Common units: volt (V), millivolt (mV), kilovolt (kV).
