2.3 kg L s⁻¹ can be written in simpler form as by the conversion of L unit to m³ , so that by putting 1L value in m³, the value can be simplified:
1 L=0.001 m³
So 2.3 kg L s⁻¹ = 2.3×0.001 kg m³ s⁻¹
=0.0023 kg m³ s⁻¹
=2.3 × 10⁻³ kg m³ s⁻¹ .
So the 2.3 kg L s⁻¹ can be written in simpler form as 2.3 × 10⁻³ kg m³ s⁻¹.
