What is the conversion of 7.03 cm to nanometers?

Answer 1

The centi- (c) prefix means 1/100 = 10⁻²

The nano- (n) prefix means 1/1,000,000,000 = 10⁻⁹

→ 1 nm = 10⁻⁹ m

→ 1 cm = 10⁻² m

→ 7.03 cm = 7.03 × 10⁻² m

= 7.03 × 10⁻² × 1/10⁻⁹ × 10⁻⁹ m

= 7.03 × 10⁻² × 10⁹ nm

= 7.03 × 10⁹⁻² nm

= 7.03 × 10⁷ nm

= 70,3000,000 nm

Answer 2

It is 703000000 nm.
