## Overview

The Fraction to Decimal Calculator simplifies the conversion of simple fractions and mixed numbers into precise decimal values and percentages. It allows users to define decimal precision up to 20 places, making it an essential tool for academic, engineering, and culinary applications where exact numerical representation is required.

## Inputs

- **Fraction Value** (text): e.g. 2 3/8 or 3/8
- **Decimal Places** (number)
- **Show Percentage** (checkbox)

## When to use

- Converting complex mixed numbers into decimals for use in digital spreadsheets or financial reports.
- Adjusting recipe measurements that use fractions into decimal format for precise kitchen scales.
- Solving mathematical problems that require high-precision decimal outputs from fractional inputs.

## How it works

- Enter a fraction or mixed number, such as '3/4' or '2 3/8', into the input field.
- Specify the desired number of decimal places for the result, with a maximum limit of 20.
- Toggle the percentage option if you need to see the equivalent percentage value alongside the decimal.
- Review the generated JSON output containing the calculated decimal and percentage values.

## Use cases

- Engineering professionals converting fractional blueprint measurements into decimal units for CAD software.
- Students and educators verifying manual fraction-to-decimal long division results for homework.
- Home cooks scaling recipes by converting fractional cup measurements into decimal grams or ounces.

## Frequently asked questions

### Can I convert mixed numbers like 2 3/4?

Yes, simply enter the whole number followed by a space and the fraction in the input field.

### What is the maximum decimal precision supported?

The tool supports configurable precision up to 20 decimal places.

### Does the tool provide percentage equivalents?

Yes, by enabling the 'Show Percentage' option, the tool will output the percentage value.

### How do I input a simple fraction?

Enter the numerator and denominator separated by a forward slash, such as '5/16'.

### Is there a limit to the number of decimal places I can set?

The tool allows you to set the precision anywhere between 0 and 20 decimal places.
