Universal Unit Converter – Convert Length, Weight, Volume & More

John was cooking a recipe he found online. The ingredients were in grams and milliliters, but his measuring tools only showed ounces and cups.

He tried to do the math in his head, got frustrated, and ended up guessing — the cake didn’t turn out right.

That’s where the Universal Unit Converter comes in. Whether it’s for cooking, science projects, travel, or fitness tracking, this tool helps you switch between length, weight, volume, temperature, speed, and time in seconds — with no mistakes.

What Is This Converter?

The Universal Unit Converter is a simple but powerful tool that translates one measurement system into another. For example:

• Length: miles ↔ kilometers, inches ↔ centimeters
  
• Weight: pounds ↔ kilograms, ounces ↔ grams
  
• Volume: liters ↔ cups, gallons ↔ milliliters
  
• Temperature: Celsius ↔ Fahrenheit ↔ Kelvin
  
• Speed: mph ↔ km/h
  
• Time: seconds ↔ minutes ↔ hours
  

Instead of memorizing formulas or Googling each one, you simply choose the category, enter your number, pick the unit, and convert.

Formula

Every conversion is based on a mathematical relationship between units. For example:

• Length: 1 inch = 2.54 cm
  
• Weight: 1 kg = 2.20462 lbs
  
• Volume: 1 liter = 4.22675 cups
  
• Temperature:
  
  • °C → °F = (°C × 9/5) + 32
    
  • °F → °C = (°F – 32) × 5/9
    
  • °C → K = °C + 273.15
    

The calculator already has these formulas programmed in, so you just enter and convert — instantly.

Step-by-Step: How the Converter Works

1. Choose a category (length, weight, volume, etc.).
   
2. Enter the value (e.g., 10).
   
3. Select the unit you want to convert from (e.g., kilometers).
   
4. Select the unit you want to convert to (e.g., miles).
