Example 5: Two containers contain 18 L 300 mL and 17 L 900 mL oil. Find the total quantity

of oil in the two containers. math Encapsulate
Solution: L mL MEASUREMEnT

1 1 Measurement of Length Measurement of Weight Conversions
Quantity of oil in the first container = 1 8 3 0 0 Olive Sunflower Centimetre(cm)- It is the smaller unit of length. Milligram(mg)- It is 1 km = 1000 m
Oil
Quantity of oil in the second container = + 1 7 9 0 0 Oil used to measure very 1 m = 1/1000 km
light things.
Total quantity of oil in both the containers = 3 6 2 0 0 Gram(g)- It is 1 m = 100 cm
1 cm = 1/100 m
used to measure
Thus, the total quantity of oil in both the containers is 36 L 200 mL. Metre(m)-It is another unit lighter weight. 1 kg = 1000 g
of length used to measure
1 g = 1/1000 kg
the longer lengths. kilogram(kg)- It is

evening. How much more milk did he sell in the evening than in the morning? Kilometre(km)-It is the heavy weights. It is the 1 mL = 1/1000 L
standard unit of weight.
Solution: bigger unit of length used 141 km Addition
