Joules to Kg Calculator

Formula

The formula to calculate the mass from energy (m) is:

\[ m = \frac{E}{c^2} \]

Where:

\( m \) is the mass in kilograms (kg)
\( E \) is the energy in joules (J)
\( c \) is the speed of light in a vacuum, approximately \( 3.00 \times 10^8 \) m/s

Joules to Kg: A conversion from energy (measured in Joules) to mass (measured in kilograms) based on Einstein’s equation \( E=mc^2 \).
Significance: Used in high-energy physics and quantum mechanics to understand the relationship between energy and mass.

Let's say the energy (E) is \( 9 \times 10^{16} \) J. Using the formula:

\[ m = \frac{9 \times 10^{16}}{(3 \times 10^8)^2} = 1 \]

So, the mass (m) is 1 kg.
