How This Metal Fraction to Decimal Chart Helps When Ordering Metal Sheets
- Precision matters! Many metals are listed in fractional inches, but cutting tolerances often require decimal or metric values.
- Example: If you need a 2mm thick copper sheet but the listing shows 5/64″, use the chart to confirm that 5/64″ = 1.98mm, making it the closest match.
- Common Metal Thicknesses:
- Copper & Brass: Usually available in 1/16″ (1.5mm), 1/8″ (3mm), and 1/4″ (6mm) thicknesses.
- Aluminium: Comes in a variety of fractions and metric sizes.
- Stainless Steel: Typically sold in gauge, fractional inches, or millimeters.
