Question

1. Express 7 kL 6 hL 5 dal 9 L 7 cL as following units:
(a) millilitres
(b) litres
(c) hectolitres
(d) kilolitres​

Answer 1

The conversions are,

7659070 mL

7659.07 L

76.5907 hectolitres.

7.65907 kilolitres.

• A unit of measurement is a magnitude which is specific of a quantity that has been established and recognised by law or convention and is used primarily as a benchmark for measuring other quantities of the same kind. A multiple of the unit of measurement can be used to express any other quantity that is related to that type.
• A length, for instance, is an example of a physical quantity. A unit of length that represents a certain, predetermined length is the metre (symbol m).
• From ancient times to the present, the definition, agreement, and applications pertaining to practical uses of units of measurement have been critical to human endeavour. It used to be quite usual to see a wide variety of unit systems. The International System of Units (SI), the updated version of the metric system, is now the accepted global standard.

Here, according to the given information, we are given that,

(a) 7 kL 6 hL 5 dal 9 L 7 cL =

$(7.10^{6}) +(6.10^{5}) +(5.10^{4}) +(9.10^{3}) +70\\=7659070 mL$

(b) 7 kL 6 hL 5 dal 9 L 7 cL =

$(7.10^{3}) +(6.10^{2}) +(5.10^{1}) +9+0.07\\=7659.07 L$

(c) Now, 7659.07 L to hectolitres = 76.5907 hectolitres.

(d) Now, 76.5907 hectolitres to kilolitres = 7.65907 kilolitres.

Hence, the conversions are,

• 7659070 mL
• 7659.07 L

• 76.5907 hectolitres.

• 7.65907 kilolitres.
