## How to Convert Inches to Millimeters

1 inch is equal to 25.4 millimeters:

1″ = 25.4mm

2 inch is equal to 50.8mm millimeters:

2″ = 50.8mm

So distance d  in millimeters (mm) is equal to the distance d in inches (″) times [25.4].

d(mm) =  d(inch) × 25.4

#### Example 1

Convert 10 inches to millimeters:

d(mm) = 10″ × 25.4 = 254mm

#### Example 2

Convert 15 inches to millimeters:

d(mm) = 15″ × 25.4 = 381mm

#### Example 3

Convert 30 inches to millimeters:

d(mm) = 30″ × 25.4 = 762mm

#### Example 4

Convert 50 inches to millimeters:

d(mm) = 50″ × 25.4 = 1270mm

#### Example 5

Convert 100 inches to millimeters:

d(mm) = 100″ × 25.4 = 2540mm

#### Example 6

Convert 200 inches to millimeters:

d(mm) = 200″ × 25.4 = 5080mm

#### Example 7

Convert 1000 inches to millimeters:

d(mm) = 1000″ × 25.4 = 25400mm
