How to use this tool?

Quickdash Calculator performs basic arithmetic and unit conversions. Follow these steps:

  1. Enter numbers – Type the first number (required) and second number (required for all operations except unit conversion alone).
  2. Choose an operation – Select from Add, Subtract, Multiply, Divide, or Percentage. For Percentage, the result is first number % of second number.
  3. Optional unit conversion – Pick a conversion (e.g., Inches → cm, °F → °C). This converts the first number and overrides the arithmetic result.
  4. Click Calculate – The result appears in green, with the formula shown below. Errors (e.g., division by zero, missing input) display in red.

Tips:

  • Use decimal numbers freely (e.g., 2.5).
  • For unit conversions, the arithmetic result is replaced by the conversion value.
  • If you select a conversion but leave the first number blank, you’ll see an error.
