The strengths of the fundamental forces in nature are typically described by their coupling constants. However, the relative strengths of the forces can be roughly quantified by comparing their magnitudes.
In particle physics, the relative strengths of the fundamental forces are often discussed in terms of their magnitudes at the scale of an atomic nucleus. Here is a rough estimate of the ratios between the strengths of the four fundamental forces:
Strong Nuclear Force: The strong nuclear force is responsible for holding atomic nuclei together and is the strongest of the four fundamental forces. Its strength is approximately 100 times stronger than the electromagnetic force.
Electromagnetic Force: The electromagnetic force is responsible for interactions between charged particles and plays a crucial role in the structure of matter. It is roughly 1/100th the strength of the strong nuclear force.
Weak Nuclear Force: The weak nuclear force is involved in certain radioactive decays and interactions of subatomic particles. It is much weaker than both the strong nuclear force and the electromagnetic force. The weak nuclear force is roughly 10^25 times weaker than the strong nuclear force.
Gravitational Force: The gravitational force is responsible for the attraction between objects with mass. In comparison to the other three fundamental forces, the gravitational force is extremely weak. It is approximately 10^39 times weaker than the strong nuclear force.
It's important to note that these ratios are approximate and represent the strengths of the forces in a specific context. The exact values may vary depending on the specific energy scale or conditions under consideration.
