Key Formulas

Ohm's Law

V=IRV = IR

Voltage = Current × Resistance.

Newton's Second Law

F=maF = ma

Force = mass × acceleration.

Conversion Formulas

To convert a value using a SI prefix: For a larger prefix (e.g., kilo): Value in base unit=Value with prefix×10exponent\text{Value in base unit} = \text{Value with prefix} \times 10^{\text{exponent}} For a smaller prefix (e.g., milli): Value in base unit=Value with prefix×10exponent\text{Value in base unit} = \text{Value with prefix} \times 10^{\text{exponent}}

System Note

Prefixes listed are used in the SI system in accordance with DIN 1301 "Units - Part 1: Unit names, unit symbols".
