Joules to Watt Seconds: 1 J equals 1 Ws. To convert joules to watt seconds, multiply by 1 (Ws = J × 1). For example, 10 J = 10 Ws.
How to Convert Joules to Watt Seconds
To convert from joules to watt seconds, multiply the value by 1. The conversion is linear, meaning doubling the input doubles the output.
Conversion Formula
- Joules to Watt Seconds:
Ws = J × 1 - Watt Seconds to Joules:
J = Ws ÷ 1

Understanding the Units
What is a Joule?
The joule is the SI derived unit of energy, equal to the work done by a force of one newton acting through a distance of one meter (1 J = 1 N·m = 1 W·s).
Named after James Prescott Joule (1818–1889), the English physicist who demonstrated the mechanical equivalent of heat.
Common contexts: physics, chemistry, engineering.
What is a Watt Second?
A watt-second is identical to one joule.
Common contexts: photography (flash energy), capacitor ratings.
