Time Dilation Calculator

Space and speed have major effects on many different aspects of life. The dilation of time is one of those. Calculate the relative time value based on the speed and time of an object.

Required Information

Time Interval (Δt):

Velocity:

Relative Time (Δt'):

What is Time Dilation?

Time dilation is a concept where time is experienced differently based on the velocity of an object. If you are moving at the speed of light you will experience time differently and this calculator can help you understand that difference in time.

How to Calculate Time Dilation

For our formula, we convert everything into meters per second, and we utilize the speed of light which is 299,792,458 meters per second. The formula is:

Δt' = Δt / √(1 - (v²/c²))

Where:

Δt' = Time interval experienced by the moving observer (dilated time)
Δt = Time interval experienced by the stationary observer (proper time)
v = Velocity of the moving object relative to the stationary observer
c = Speed of light

Why Time Dilation is Important

We know what you are thinking, who would ever need to know or worry about time dilation? While it is a fair question since 99% of people are not affected by it in a large way currently, this can be important for space travel and other missions to space or other planets that may take place in the future.

This information can be used for mission planning and for training and preparation reasons. There is nothing like the feeling of time dilation, next to no one has felt it so preparing future space travelers as much as possible is key.

How to Use the Time Dilation Calculator

This tool is as easy to use as 1 ,2 ,3. The steps involved are:

Enter the time interval, which is the amount of time experienced for the moving subject.

Enter the velocity of the moving subject.

Hit calculate and get your answer instantly! Remember, your result is the amount of time that someone would experience when they are not moving at such fast speeds.

Understanding Your Results

The concept of time dilation is still new to most people. It can be confusing to understand and thoroughly follow along with. When using our tool you are entering the amount of time that the person or subject experiences when they are moving at whatever speed they are going.

Then when you hit calculate you are getting the relative time which is the amount of time that would pass for someone not moving to experience the same situation. The faster you are moving, the slower time is going.

Time Dilation - Frequently Asked Questions

Time slows down as you travel faster because momentum bends the fabric of spacetime causing time to pass slower.

It is hard to say whether or not people can actually feel and notice time dilation. Some who have traveled to space have commented that they do feel as if they time traveled.

It is believed that you would age slightly slower or faster depending on the gravitational field.

One year near a black hole could be more like 80 years due to time dilation.
