This converter allows you to convert watts [W] to joules per second [J/s] or joules per second [J/s] to watts [W]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert watts to joules per second
watt [W] and joule per second [J/s] are two units that have the same value, even though they have different names. For this reason, no conversion is necessary. 1 watt [W] therefore corresponds to 1 joule per second [J/s]
- Joules per second [J/s] = watts [W]
Convert joules per second to watts
Although joule per second [J/s] and watt [W] have different names, they have the same value. This means that 1 joule per second [J/s] corresponds exactly to 1 watt [W]. It is therefore not necessary to convert between the two units.
- Watts [W] = joules per second [J/s]

Resistance
Electrical resistance is often expressed in ohms or kiloohms. However, it is also possible to use statohms or deciohms. The resistance converter is ideal for converting between different units of resistance.

Speed
While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
