# Fraction Decimal Converter Convert between fractions and decimals with support for mixed numbers, improper fractions, and various decimal formats > Canonical page: https://elysiatools.com/en/tools/fraction-decimal-converter - **Category:** Math & Numbers - **Keywords:** fraction, decimal, convert, ratio, mixed number, improper fraction, mathematics, number conversion ## Overview The Fraction Decimal Converter is a versatile tool designed to seamlessly switch between fractional and decimal numerical formats. Whether you are working with mixed numbers, improper fractions, or precise decimal values, this utility provides accurate conversions with customizable settings for simplification and precision. ## Inputs - **Numbers Input** (textarea): Enter fractions or decimals separated by commas, spaces, or newlines: 1/2, 3 1/4, 5/8 0.25, 3.75, 0.125 1 2/3, 0.666, 7/3 - **Conversion Mode** (select) - **Simplify Fractions** (checkbox) - **Show Mixed Numbers** (checkbox) - **Max Decimal Places** (number): Maximum decimal places for output (0-20) - **Decimal→Fraction Tolerance** (number): Tolerance for decimal to fraction approximation (e.g., 1e-10) - **Show Conversion Steps** (checkbox) ## When to use - When you need to convert complex mixed numbers or improper fractions into readable decimal values for calculations. - When you must transform precise decimal measurements into simplified fractions for engineering or construction blueprints. - When you are verifying mathematical homework or data sets that require consistent formatting across different number types. ## How it works - Enter your fractions or decimals into the input area, separating multiple values with commas, spaces, or newlines. - Select your preferred conversion mode, such as Fraction to Decimal, Decimal to Fraction, or both. - Adjust optional settings like 'Simplify Fractions' or 'Max Decimal Places' to tailor the output to your specific requirements. - Click the convert button to generate your results instantly. ## Use cases - Converting cooking measurements from decimals to fractions for standard measuring cups. - Standardizing data entries in spreadsheets by converting mixed fractions into uniform decimal formats. - Assisting students in checking their work for algebra and arithmetic assignments involving ratio conversions. ## Frequently asked questions ### Can this tool handle mixed numbers? Yes, the tool fully supports mixed numbers (e.g., 3 1/4) and improper fractions. ### How do I ensure my fractions are simplified? Simply check the 'Simplify Fractions' box in the settings before running your conversion. ### What is the maximum number of decimal places I can set? You can set the output precision anywhere from 0 to 20 decimal places. ### Can I convert multiple numbers at once? Yes, you can input a list of numbers separated by commas, spaces, or newlines to convert them in a single batch. ### What does the 'Decimal to Fraction Tolerance' setting do? It defines the precision level for approximating decimals as fractions, allowing you to control how closely the fraction matches the decimal input. ## Related tools - [Number Converter](https://elysiatools.com/en/tools/number-converter): Convert numbers between different formats (decimal, binary, hexadecimal, octal) - [Unit Converter with Formula Display](https://elysiatools.com/en/tools/unit-converter-with-formula): Convert common physical, chemistry, cooking, medical, and information units with the formula and dimensional analysis visible. - [Angle Unit Converter](https://elysiatools.com/en/tools/angle-converter): Convert between different angle units (degrees, radians, gradians, minutes, seconds, etc.) - [Area Unit Converter](https://elysiatools.com/en/tools/area-converter): Convert between different area units (square meters, square feet, acres, hectares, etc.) - [Carmichael Function λ(n) Calculator](https://elysiatools.com/en/tools/carmichael-function): Group exponent λ(n) from prime factorization with φ(n) comparison, primitive-root existence, Korselt's Carmichael-number detection, and optional sample-unit verification. - [Chinese Remainder Theorem Solver (System of Congruences)](https://elysiatools.com/en/tools/chinese-remainder-theorem): Generalized pairwise-merge CRT for 2–20 congruences: coprime moduli give the product modulus, consistent non-coprime moduli give the lcm, inconsistent systems are rejected. - [Data Storage Unit Converter](https://elysiatools.com/en/tools/data-storage-converter): Convert between different data storage units (bit, byte, KB, MB, GB, TB, etc.) - [Density Unit Converter](https://elysiatools.com/en/tools/density-converter): Convert between different density units (kg/m³, g/cm³, lb/ft³, etc.) ## Samples - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Android Image Processing Java Samples](https://elysiatools.com/en/samples/android-image-processing-java): Android Java image processing examples including reading/saving images, scaling, and format conversion - [Android Image Processing Kotlin Samples](https://elysiatools.com/en/samples/android-image-processing-kotlin): Android Kotlin image processing examples including reading/saving images, scaling, and format conversion - [Web Image Processing Rust Samples](https://elysiatools.com/en/samples/web-image-processing-rust): Web Rust image processing examples including image read/save, scaling, and format conversion ## Related content - [Math and Number Conversion Workflow](https://elysiatools.com/en/hubs/math-&-numbers-convert): Convert measurements, number bases, fractions, scientific notation, Roman numerals, and byte or bit values with a clear precision check.
