⚙️ Horsepower (HP) to Kilowatt (kW) Converter
This calculator converts motor power from horsepower (HP) to kilowatts (kW) using the standard conversion factor for accurate electrical and mechanical power estimation.
Formula: P(kW) = P(HP) × 0.7457
where: P(kW) = Power in kilowatts | P(HP) = Power in horsepower
🧪 Volume Unit Converter
Convert between common volume units such as liters, cubic meters, gallons, and more — ideal for engineering, laboratory, and industrial calculations.
Formula: Valueto = Valuefrom × (Factorfrom / Factorto)
where: 1 m³ = 1000 L | 1 L = 1000 mL | 1 gal = 3.78541 L | 1 cup = 0.236588 L
⚖️ Weight Unit Converter
Convert between common weight and mass units such as kilograms, grams, pounds, and ounces — ideal for engineering, science, and general calculations.
Formula: Valueto = Valuefrom × (Factorfrom / Factorto)
where: 1 kg = 1000 g | 1 lb = 0.453592 kg | 1 oz = 0.0283495 kg | 1 t = 1000 kg
🧮 Material Volume to Weight Converter
Calculate material weight from its density and volume. Ideal for estimating material requirements in engineering, manufacturing, and design applications.
Formula: Weight = Density × Volume
where: 1 m³ = 1000 L | 1 ft³ = 0.0283168 m³ | 1 cm³ = 1e-6 m³
🌡️ Temperature Unit Converter
Instantly convert between Celsius, Fahrenheit, Kelvin, and Rankine. Perfect for engineering, science, and everyday use.
Formula: Tto = f(Tfrom) according to unit-specific relationships.
where: °F = (°C × 9/5) + 32 | K = °C + 273.15 | °R = (°C + 273.15) × 9/5
🚀 Speed Unit Converter
Convert between common speed units such as meters per second, kilometers per hour, miles per hour, and knots — ideal for engineering, transport, and weather analysis.
Formula: Valueto = Valuefrom × (Factorfrom / Factorto)
where: 1 m/s = 3.6 km/h | 1 mph = 0.44704 m/s | 1 ft/s = 0.3048 m/s | 1 knot = 0.514444 m/s
📐 Area Unit Converter
Convert between common area units such as square meters, acres, hectares, square feet, and more — ideal for engineering, construction, and land measurement.
Formula: Valueto = Valuefrom × (Factorfrom / Factorto)
where: 1 m² = 0.0001 cm² | 1 ft² = 0.092903 m² | 1 acre = 4046.856 m² | 1 ha = 10000 m²
📏 Length Unit Converter
Convert between common length and distance units such as meters, centimeters, inches, feet, yards, and miles — ideal for engineering, design, and everyday conversions.
Formula: Valueto = Valuefrom × (Factorfrom / Factorto)
where: 1 m = 100 cm | 1 ft = 0.3048 m | 1 mi = 1609.34 m
