The ratio of 1/2 kg flour to cups.

1/2 kg flour : 4 full cups of flour.

4 full cups of flour will be equivalent to half kilo of flour. That is 1/2 kilo of flour.

The cup to be used in measuring 1/2 kilo flour should be accurate to give the right measurements.

The measuring cups used to measure flour should be in milliliters.

The weight of flour in 1 ml is equivalent to 0.53 grams. That is to say; 0.53 grams of flour is equivalent to 1 ml.

Formula: 0.53 grams × 1 milliliter in cup = 0.53 grams

Therefore, 1 gram of flour must be increased to make the exact 1 milliliter in cup. That is to say; 1 full cup of flour plus a few grams of flour to make the exact milliliter in cups.
