To convert the diameter of a penny from centimeters (cm) to meters (m), millimeters (mm), and kilometers (km), you can use the following conversion factors:
- 1 cm = 0.01 m
- 1 cm = 10 mm
- 1 cm = 0.00001 km
Given that the diameter of a penny is 1.90 cm, let’s convert it to each unit:
Conversion to Meters (m):
To convert cm to m, multiply the value in cm by 0.01:
1.90 cm × 0.01 = 0.019 m
So, the diameter of a penny is 0.019 meters.
Conversion to Millimeters (mm):
To convert cm to mm, multiply the value in cm by 10:
1.90 cm × 10 = 19 mm
So, the diameter of a penny is 19 millimeters.
Conversion to Kilometers (km):
To convert cm to km, multiply the value in cm by 0.00001:
1.90 cm × 0.00001 = 0.000019 km
So, the diameter of a penny is 0.000019 kilometers.
These conversions help you understand the size of a penny in different units of measurement.
