Torque Calculator
Calculate torque easily using force and lever arm distance. Our Torque Calculator helps engineers and mechanics determine rotational force in seconds.
moment of force calculator:
Torque is used to measure the ability of any force to cause an object to rotate about an axis. This is made easy by the Torque Calculator that applies the formula Torque = Force x Distance. All one has to do is enter the applied force and the length of the lever arm, and get the value of torque immediately. It is needed in motor performance analysis, tightening wrenches, and rotational mechanics experiments.
density conservation tool Formula:
The Density Calculator helps determine the density of a substance or material by dividing its mass by its volume using the formula \( P = \frac{m}{V} \) Simply input mass (grams, kilograms, pounds, etc.) and volume (cm³, m³, liters, etc.) to calculate the density in desired units such as g/cm³ or kg/m³. This tool is essential for physics students, engineers, and materials scientists working with solids, liquids, and gases. It supports multiple unit conversions, giving accurate, real-time results for laboratory experiments, engineering designs, and material property comparisons. You can also reverse-calculate — find mass from density and volume, or volume from density and mass. This mass-volume relationship tool helps visualize how materials differ in compactness, allowing precise analysis for scientific and industrial applications.
⚡ Work & Installation (Input → Output):
Inputs:
- Mass (m) — e.g., grams, kilograms, pounds
- Volume (V) — e.g., cubic centimeters, cubic meters, liters
- Optional: unit conversion selector (input/output units)
Process / Work:
- Convert all entered values into consistent units (SI preferred).
- \( P = \frac{m}{V} \)
- \( m = p \times V \) 2. \( V = \frac{m}{p} \)
- Display density with appropriate unit symbols and significant digits.
Outputs:
- Calculated density (kg/m³, g/cm³, etc.)
- Optional conversions (to multiple units)
- Step-by-step formula explanation
Testing and Final Adjustments:
To ensure accuracy, test the Density Calculator using standard materials like water (density = 1000 kg/m³), aluminum (2700 kg/m³), and gold (19300 kg/m³). Enter mass and volume values and verify the calculated density matches the known reference. Test multiple unit combinations (g/cm³, lb/ft³, kg/m³) and confirm that unit conversions remain consistent. Validate edge cases such as very small (microscopic) or large-scale volumes. For precision, verify floating-point rounding to 3–5 significant digits. Include warnings for division by zero (volume = 0) and invalid inputs. Adjust UI to automatically switch output units depending on selected system (metric or imperial). For final testing, compare results with known physical constants and online references to ensure reliability before publishing.
Frequently Asked Questions - Torque Calculator:
What is torque?
Torque is the rotational force that causes an object to rotate around an axis.
What is the torque formula?
Torque = Force × Distance from pivot point.
What are the units of torque?
Newton-meter (N·m), pound-foot (lb·ft), and kilogram-centimeter (kg·cm).
What is lever arm distance?
It is the perpendicular distance between the pivot and the force line.
Can torque be negative?
Yes, depending on the rotation direction (clockwise or counterclockwise).
Is torque the same as power?
No, torque measures rotational force; power measures work per time.
Can I use this for motors?
Yes, use motor torque and speed to calculate power output.
What affects torque value?
Force magnitude and lever arm length determine torque size.
Does angle affect torque?
Yes, maximum torque occurs when the force is perpendicular to the lever.
Is this calculator free?
Yes, it’s a free online tool for physics and engineering calculations.
