0.0532g/250ml x 1000mg/1g x 1000ml/1 L = mg/L
Step 1
is the unit cancellation step. The gram (g) unit from the top (or numerator) of the fraction is canceled from the bottom (or denominator), the ml unit from the top (or numerator) of the fraction is canceled from the bottom (or denominator) leaving only the (mg/L) unit
