Master fraction to decimal conversions with three simple methods
Each row shows a fraction and its decimal equivalent. Common fractions like 1/2, 1/4, and 3/4 are highlighted for quick reference.
Example:
1/2 = 0.5 = 50%
3/8 = 0.375 = 37.5%
Tip: Start by memorizing halves, quarters, and eighths - these form the foundation for all other fractions.
Choose the right precision level for your needs. Higher denominators provide more accuracy but create longer charts.
Precision Levels:
1/8 - Basic (8 fractions)
1/16 - Standard (16 fractions)
1/32 - Woodworking (32 fractions)
1/64 - High Precision (64 fractions)
Note: For most educational purposes, 1/16 or 1/32 precision provides the perfect balance between detail and usability.
💡 Pro Tip: Use this chart as a quick reference instead of calculating every time!
Discover how students, professionals, and hobbyists use fraction to decimal charts in their work
Essential study tool for students learning fraction concepts, decimal equivalents, and percentage conversions. Helps build number sense and mental math skills.
💡 Recommended: 1/16 precision with percentages
Critical reference when reading tape measures, setting router bits, or calculating cut dimensions. Convert fractional inch measurements to decimals for precision tools.
💡 Recommended: 1/32 or 1/64 precision with inch marks
Helpful for recipe conversions when scaling measurements or converting between cup fractions and decimal ounces. Ensures precise ingredient ratios for consistent results.
💡 Recommended: 1/8 or 1/16 precision
The Formula
Example Conversion:
Problem: Convert 3/4 to decimal
Step 1: Identify numerator (3) and denominator (4)
Step 2: Divide: 3 ÷ 4 = 0.75
Answer: 3/4 = 0.75 (or 75%)
Mastering these common fractions will make mental math much faster. These form the foundation of the fraction system:
💡 Memory Trick: Notice patterns! All odd numerators with denominator 8 end in .125, .375, .625, or .875. Once you know the pattern, you can calculate any fraction mentally.
Always reduce fractions before converting
Compare to fractions you know
Use fraction relationships

Standard decimal equivalents for blueprint reading and programming.
| Fraction | Decimal | MM | Tap Drill |
|---|---|---|---|
| 1/64 | 0.0156 | 0.397 | #78 |
| 1/32 | 0.0312 | 0.794 | #68 |
| 3/64 | 0.0469 | 1.191 | #56 |
| 1/16 | 0.0625 | 1.588 | #52 |
| 1/8 | 0.1250 | 3.175 | #30 |
Practical Tip:
Count the smallest lines (1/16s). If you count 5 small lines past the inch mark, that's 5/16". If you count 4, that's 4/16" which simplifies to 1/4".

1/16" is 0.0625, 1/8" is 0.125, and 1/4" is 0.25. These are the most common increments used in US construction and woodworking.
For general framing, 1/16 is sufficient. For cabinetry and furniture making, 1/32 precision is the standard. If you are using a CNC or high-end stationary tools, you should reference the 1/64 (0.0156) decimal equivalents.
Simply divide the numerator (top number) by the denominator (bottom number). For example, 5/8 is 5 ÷ 8 = 0.625.
Yes. In the US standard measurement system, 3/8 inch is exactly 0.375 in decimal form. It is a critical size for many bolt and screw diameters.
Recurring decimals (like 1/3 = 0.333...) occur when the denominator's prime factors are not just 2 or 5. Our chart rounds these to professional-grade precision for practical workshop use.
Most standard tape measures only go down to 1/16. To measure 1/64, you typically need a precision machinist rule or a digital caliper which shows decimal or fractional 64ths.
