সূত্র
The fundamental relationship between torque and horsepower:
HP = Torque (ft-lb) × RPM / 5,252
The constant 5,252 is derived from:
• 1 HP = 33,000 ft·lb/min
• 5,252 = 33,000 / (2π)
For newton-meters:
HP = Torque (Nm) × RPM / 7,121
To convert torque units:
• 1 ft-lb = 1.35582 Nm
• 1 Nm = 0.73756 ft-lb
To convert power:
• 1 HP = 745.7 watts
• 1 PS (metric HP) = 735.5 watts
ব্যবহারের ক্ষেত্র

প্রো টিপস
- Always verify the unit system (metric vs imperial) before converting.
- For high-precision work, use the formula display to verify calculations.
- Bookmark common conversions for quick access in future sessions.
- Use the conversion table to estimate values without entering numbers.
- Remember that some units (like temperature) have offset differences, not just scale.
- The swap button is useful for bidirectional conversion workflows.
এড়ানোর সাধারণ ভুলসমূহ

উদাহরণ
Example: Convert 100 Nm of torque at 4,000 RPM to horsepower. First convert to ft-lb: 100 × 0.73756 = 73.76 ft-lb. Then HP = 73.76 × 4,000 / 5,252 ≈ 56.2 HP.
