Question

Convert the following in to SI units without changing its values

A. 4000 g

b. 2.4 km
​

Answer 1

#A

`\boxed{\sf 1kg=1000g}`

`\\ \sf\longmapsto 4000`

`\\ \sf\longmapsto (4000)/(1000)`

`\\ \sf\longmapsto 4kg`

#B

`\boxed{\sf 1km=1000m}`

`\\ \sf\longmapsto 2.4km=2.4(1000)`

`\\ \sf\longmapsto 2400m`

Answer 2

A. The S.I unit of mass is kg . therefore we have to convert 4000g into kg from gram

i.e 4000g = 4 kg

B. The S.I unit of length is meter. so we have to convert 2.4 km into meters,

i.e 2.4 km = 2400 m
