The length conversion chart in the SI system is,

**Example,

• 12 km = 12 × 1000 m = 12000 km
• 20 m = 20 × 100 cm = 2000 cm

Inch

In SI system we use decimal system to convert various units into its sub units. In the SI system some of the important units are,

• SI Unit of Length: Meter(m)
• SI Unit of Weight: Kilogram(kg)
• SI Unit of Time: Second(s)

Apart form these three SI units there are other SI units of various quantities.

Length Conversion Examples

We have given some solved examples on Length Conversion for you.

**Example 1: Convert 2000 m to km.

**Solution:

We know that,

• 1000 m = 1 km

1 m = 1/1000 Km

2000 m = 2000 × 1/1000 = 2 Km

**Example 2: Convert 20 feet to m.

**Solution:

We know that,

• 1 ft = 0.3048 m

20 ft = 20 × 0.3048 = 6.096 m

**Example 3: Convert 25 mm to cm

**Solution:

We know that,

• 1 mm = 0.1 cm

25 mm = 25 × 0.1 = 2.5 cm

**Example 4: Convert 12 inches to feet.

**Solution:

We know that,

• 1 inch = 1/12 foot

12 inches = 12 × 1/12 foot

12 inches = 1 feet
