21 micrometers (μm) = 2.1e-8 kilometers (km)
Round to:
km + Meters:2.1e-5 m
Step-by-Step Solution
1Write the conversion factor:
1 kilometer = 1e9 micrometers
2Divide the value by the conversion factor:
21 ÷ 1e9 = 2.1e-8
3Result:
21 micrometers (μm) = 2.1e-8 kilometers (km)
↔ Kilometers to Micrometers
