Instantly calculate pulley ratios, belt length, speed, and motor RPM. The ultimate tool for mechanical engineers, technicians, and DIYers.
Pulley Calculator is the ultimate, all-in-one engineering tool designed for mechanical engineers, technicians, machinists, and DIY enthusiasts. Seamlessly calculate and design belt drive systems right from your pocket with a clean, intuitive, and modern interface.
Whether you are working with industrial machinery, automotive setups, or custom workshop projects, this app eliminates guesswork and complex formulas, delivering precise mechanical data instantly.
### KEY FEATURES:
1. BELT SPEED CALCULATOR
• Instantly compute linear belt speed (v in m/sec, ft/sec, mph, or km/h).
• Dynamically solve for any missing variable: input Pulley Diameter (D) and RPM to get Speed, or input Speed and Diameter to find the required RPM.
2. BELT LENGTH CALCULATOR
• Calculate the exact length of your belt system with high precision.
• Input the Large Pulley Diameter (D1), Small Pulley Diameter (D2), and Center Distance (A) to get the required belt length instantly.
3. PULLEY RATIO CALCULATOR
• Determine the precise mechanical drive ratio between two connected pulleys.
• Input D1 and D2 to visualize and compute the exact transmission ratio (e.g., 1 : 2.50) to optimize torque and RPM outputs.
4. BUILT-IN UNIT CONVERTER
• Fast and comprehensive unit conversion utility directly inside the app.
• Speed Converter: Seamlessly switch between Km/h, ft/sec, mph, and m/sec.
• Power Converter: Instantly convert Kilowatts (kW) to Horsepower (HP) and vice versa.
### WHY YOU'LL LOVE IT:
• Interactive & Simple UI: Designed for quick on-site calculations. Use fields on the fly without confusing nested menus.
• Real-time Calculations: Results update dynamically as you type your dimensions.
• Universal Engineering Tool: Perfect for V-belts, timing belts, flat belts, and custom pulley setups.
• Lightweight & Fast: No lag, no unnecessary permissions—just raw, functional calculation when you need it most.
