What is unit conversion?

Unit conversion involves the change of unit of a substance from one base to another.

Converting 1.5 x 10⁸ Gm to m

1.5 x 10⁸ Gm = 1.5 x 10⁸ x 10⁹ m = 1.5 x 10¹⁷ m

Converting 2.6 x 10⁻⁵ nm to Mm

2.6 x 10⁻⁵ nm = 2.6 x 10⁻⁵ x 10⁻⁹ x 10⁻⁶ m = 2.6 x 10⁻²⁰ Mm

Converting 2.72 x 10⁻⁵ μm to m

2.72 x 10⁻⁵ μm =  2.72 x 10⁻⁵  x 10⁻⁶ m =  2.72 x 10⁻¹¹ m

Converting 2.56 x 10⁻³ cm to km

2.56 x 10⁻³ cm = 2.56 x 10⁻³ x 10⁻² m x 10⁻³ km/m = 2.56 x 10⁻⁸ km

Converting 2 hours to seconds

2 hr = 2 x 3600 s = 7,200 seconds

Converting 2 h 30min to seconds

2 h 30 min = 7,200 seconds + 1800 s = 9,000 seconds
