## Metric to SAE Converter

Use our **metric to sae calculator** to **convert **measurements from the **metric system** to the **SAE (Society of Automotive Engineers)** system, also known as the **imperial or standard system**.

This calculator is particularly useful for engineers, mechanics, and DIY enthusiasts who frequently work with both measurement systems.

The **metric system**, used in most countries worldwide, is based on units of 10 and uses measurements like **millimeters **(mm), **centimeters **(cm), and **meters **(m). On the other hand, the **SAE system**, primarily used in the United States, relies on **inches **and **fractions of inches**.

The **metric to sae conversion **saves time and reduces errors that might occur during manual calculations.

## Metric to SAE Conversion Formula

The fundamental formula for converting metric measurements to SAE is:

**1 inch = 25.4 millimeters**

Based on this, we can derive the following formula:

**SAE (inches) = Metric (mm) ÷ 25.4**

Here are some common conversions:

### Length

**Millimeters to Inches**: $$ \text{Inches} = \text{Millimeters} \times 0.0393701 $$**Centimeters to Inches**: $$ \text{Inches} = \text{Centimeters} \times 0.393701 $$**Meters to Feet**: $$ \text{Feet} = \text{Meters} \times 3.28084 $$**Meters to Inches**: $$ \text{Inches} = \text{Meters} \times 39.3701 $$

### Weight

**Grams to Ounces**: $$ \text{Ounces} = \text{Grams} \times 0.035274 $$**Kilograms to Pounds**: $$ \text{Pounds} = \text{Kilograms} \times 2.20462 $$

### Volume

**Milliliters to Fluid Ounces**: $$ \text{Fluid Ounces} = \text{Milliliters} \times 0.033814 $$**Liters to Gallons**: $$ \text{Gallons} = \text{Liters} \times 0.264172 $$

### Temperature

**Celsius to Fahrenheit**: $$ \text{Fahrenheit} = \left(\text{Celsius} \times \frac{9}{5}\right) + 32 $$

## How do you convert metric to SAE?

Converting metric measurements to SAE involves the following steps:

**Start with the metric measurement**in millimeters (mm).**Divide the metric value by 25.4**to get the equivalent in inches.**Round the result**to the nearest fraction of an inch commonly used in the**SAE system**.

For example, let’s convert 10 mm to **SAE**:

- Start with 10 mm
- 10 ÷ 25.4 = 0.3937 inches
- Round to the nearest fraction: 0.3937 is closest to 3/8 inch (0.375)

**10 mm **is approximately **3/8 inch** in the **SAE system**.

- 10 mm ≈ 0.394 inches
- 15 mm ≈ 0.591 inches
- 18 mm ≈ 0.709 inches
- 17 mm ≈ 0.669 inches
- 22 mm ≈ 0.866 inches
