Engineering Unit Conversion Calculator – Convert Force, Pressure, Torque Instantly

Every engineer knows the struggle: you’re reading a research paper that lists pressure in bar, but your simulation software only accepts psi. Or you’re working on torque values and half your data comes in Nm while the rest is in lb-ft. Doing the math manually every time is slow, error-prone, and distracting from the real work.

That’s why an Engineering Unit Conversion Calculator is so valuable. Enter a number, pick the units, and the tool instantly converts between common engineering measurements like force, pressure, and torque. No more memorizing conversion factors — the calculator does the heavy lifting.

Why This Converter Matters

• Saves time: Engineers and students handle unit mismatches daily. A calculator eliminates manual conversions.
  
• Avoids mistakes: A single wrong unit can ruin a calculation or design. Automated conversions reduce risk.
  
• Universal use: Whether you’re in structural engineering, fluid mechanics, automotive design, or physics class, force/pressure/torque conversions are everywhere.
  
• Supports learning: For students, seeing values switch between systems (SI ↔ Imperial) reinforces understanding.
  

What You Can Convert

This calculator focuses on three engineering “workhorse” quantities:

1. Force

• Newton (N)
  
• Kilonewton (kN)
  
• Pound-force (lbf)
  
• Kilogram-force (kgf)
  

2. Pressure

• Pascal (Pa)
  
• Bar
  
• Atmosphere (atm)
  
• Pounds per square inch (psi)
  
• Torr / mmHg
  

3. Torque

• Newton-meter (Nm)
  
• Kilonewton-meter (kNm)
  
• Pound-foot (lb-ft)
  
• Pound-inch (lb-in)
  

The Conversion Formula

Unit conversions all rely on a conversion factor. The general formula is:

Value in Target Unit=Value in Source Unit×Conversion Factor\text{Value in Target Unit} = \text{Value in Source Unit} \times \text{Conversion Factor}Value in Target Unit=Value in Source Unit×Conversion Factor

Examples:

• 1 bar = 14.5038 psi
  
• 1 Nm = 0.73756 lb-ft
  
• 1 lbf = 4.44822 N
  

The calculator has these factors built in. You just select “from unit” and “to unit,” and it multiplies by the correct factor automatically.

How the Calculator Works

1. Enter a value (e.g., 250).
   
2. Choose the starting unit from the drop-down (say 250 Nm of torque).
   
3. Choose the target unit you want (lb-ft).
   
4. The calculator looks up the conversion factor (1 Nm = 0.73756 lb-ft).
   
5. It multiplies: 250 × 0.73756 = 184.39 lb-ft.
   
6. Your result displays instantly.
   

This way, you can switch between SI and Imperial units with just a couple of clicks.

Examples

• Force Example: 500 N → ? lbf
  
  • 1 N = 0.22481 lbf
    
  • 500 × 0.22481 = 112.4 lbf
    
• Pressure Example: 2 atm → ? bar
  
  • 1 atm = 1.01325 bar
    
  • 2 × 1.01325 = 2.03 bar
    
• Torque Example: 120 lb-ft → ? Nm
  
  • 1 lb-ft = 1.35582 Nm
    
  • 120 × 1.35582 = 162.7 Nm
