Momentum Unit Converter
Convert between SI, Imperial, and extended density-style units (via kg/m³ base).
Momentum Unit Converter
A Momentum Unit Converter is a practical tool used to convert momentum values between different measurement units. Momentum is a fundamental concept in physics, especially in mechanics and motion-related calculations. When working with scientific formulas, lab data, or engineering problems, converting momentum units correctly is essential for accurate results.
This guide explains what momentum is, how a momentum unit converter works, the formulas involved, and common momentum units used in physics.
What Is Momentum?
In physics, momentum is defined as the product of an object’s mass and velocity. It describes how much motion an object has and the difficulty involved in stopping it.
The standard momentum equation is:
Momentum (p) = Mass (m) × Velocity (v)
Because mass and velocity can be expressed in different units, momentum can also appear in several unit forms.
Common Momentum Units
Momentum units depend on the units used for mass and velocity. Some of the most common momentum units include:
- kilogram meter per second (kg·m/s) – SI unit
- newton second (N·s)
- gram meter per second (g·m/s)
- kilogram kilometer per hour (kg·km/h)
- pound foot per second (lb·ft/s)
- slug foot per second (slug·ft/s)
A momentum unit converter helps convert between these units without manual calculations.

Why Use a Momentum Unit Converter?
Using a momentum unit converter is important when:
- Solving physics problems with mixed unit systems
- Converting lab or experimental data
- Comparing momentum values from different sources
- Working with SI and imperial units
- Studying mechanics, collisions, and motion
Manual conversion can be time-consuming and prone to error, especially with compound units.
How Momentum Unit Conversion Works
Momentum unit conversion relies on converting mass units and velocity units separately, then combining them correctly.
For example:
- 1 newton second (N·s) is equal to 1 kg·m/s
- Converting from kg·m/s to lb·ft/s requires converting kilograms to pounds and meters to feet
A momentum unit converter calculator handles all of these steps automatically.
Momentum Unit Conversion Examples
Here are a few common examples of momentum unit conversions:
- 1 kg·m/s to N·s
1 kg·m/s = 1 N·s - 1000 g·m/s to kg·m/s
1000 g·m/s = 1 kg·m/s - 1 kg·m/s to lb·ft/s
≈ 0.7376 lb·ft/s
These examples show why a converter is useful for quick and accurate results.
Momentum Unit Conversion Table
| Momentum Unit | Equivalent in kg·m/s |
|---|---|
| 1 N·s | 1.000 |
| 1000 g·m/s | 1.000 |
| 1 kg·km/h | 0.2778 |
| 1 lb·ft/s | 1.356 |
| 1 slug·ft/s | 14.594 |
