Momentum Calculator

The Momentum Calculator quickly converts mass and velocity into momentum. Whether you’re studying physics, working on a lab report, or building a motion simulation, this tool gives you instant, clear results in either kg·m/s or N·s format.

Momentum is a key concept in motion and force. This tool uses the formula:

p = mass × velocity

and lets you toggle output style, rounding, and verbosity. Everything updates live just type in your values, and you’ll see the result right away. You can also copy the final output to your clipboard with one click.

How to Use:

To use the calculator, enter two values:

• Mass (in kilograms)
• Velocity (in meters per second)

Then adjust the formatting using the following controls:

Toggles:

• Round result Rounds the final number to four decimal places.
• Show unit Appends either kg·m/s or N·s to the output.
• Verbose output Displays the step-by-step breakdown of the formula: p = m × v.

Modes:

Use the Unit Format setting to choose:

• kg·m/s The standard unit for momentum.
• N·s Equivalent unit (newton-seconds), often used in applied mechanics.

Buttons:

• Calculate Runs the formula and updates the output. (It also updates live automatically.)
• Copy Copies the result to your clipboard and shows a visual “Copied!” message with flashing confirmation.

What Momentum Calculator can do:

Let’s say you enter a mass of 75 kg and a velocity of 3.2 m/s. The output will be:

240 kg·m/s

Switch to verbose mode, and you’ll see:

p = m × v
= 75 × 3.2
= 240 kg·m/s

You can copy this result directly into a lab sheet, report, or calculator app.

Example:

Suppose you input:

Mass: 75 kg  
Velocity: 3.2 m/s

With “Round result”, “Show unit”, and “Unit Format: kg·m/s” selected, the output will be:

240.0000 kg·m/s

If you toggle “Verbose output”, the result becomes:

p = m × v  
= 75 × 3.2  
= 240.0000 kg·m/s

Now switch the unit format to N·s, and you’ll see:

240.0000 N·s

And if you disable “Round result”, you’ll get:

240 N·s

This tool helps you calculate momentum (p = m × v) in real-time with flexible output options for rounding, units, and step-by-step breakdown perfect for physics students, engineering problems, or lab work.
