Convert 145.0 mm to meters and express the answer to the correct number of significant digits.

Solution:

Measurement refers to the comparison of an unknown quantity with a known quantity.

The result of the measurement is a numeric value with certain units.

Given, 145.0 mm

We have to convert 145.0 mm to meters.

We know, 1 meter = 1000 mm

So, 1 mm = 1/1000 m

1 mm = 0.001 m

= 0.145 m

Therefore, the converted value is 0.1450 m.

Example:

Convert 188.0 mm to meters and express the answer to the correct number of significant digits.

Solution:

Given, 188.0 mm

We have to convert 188.0 mm to meters.

We know, 1 meter = 1000 mm

So, 1 mm = 1/1000 m

1 mm = 0.001 m

Now, 188.0 mm = 188.0 × 0.001

= 0.1880 m

Therefore, the converted value is 0.188 m.
