Practice worksheet for measuring length with conversion problems.

Let’s solve each part step by step.

Q1: Fill in the blanks

a) The short form of metre is m.
→ This is standard abbreviation.

b) 10 m = ? cm
→ We know 1 m = 100 cm, so 10 m = 10 × 100 = 1000 cm

c) We measure length and distance in metres and centimetres.
→ These are common units for measuring length. (Also acceptable: kilometres, millimetres — but since it says “and”, two most basic ones are expected.)

d) 16 m 27 cm = ? cm
→ Convert metres to cm: 16 m = 16 × 100 = 1600 cm
→ Add 27 cm → 1600 + 27 = 1627 cm

e) 18 km 15 m = ? m
→ 1 km = 1000 m, so 18 km = 18 × 1000 = 18000 m
→ Add 15 m → 18000 + 15 = 18015 m

f) The length of cloth is measured in metres.
→ Cloth is usually sold by the metre.

g) 44 m = ? cm
→ 44 × 100 = 4400 cm

h) 91 km = ? m
→ 91 × 1000 = 91000 m

i) The bigger unit of length is kilometre.
→ Among mm, cm, m, km — kilometre is biggest.

j) 1 km = ? m
→ Standard conversion: 1000 m

Q2: True / False

a) 430 cm = 430 m → False
→ Because 100 cm = 1 m, so 430 cm = 4.3 m, not 430 m.

b) Distance between Chandigarh and Delhi is 10 m → False
→ That’s way too small! It’s about 250 km. 10 m is like a room size.

c) 60 km + 40 m + 30 m + 10 m = 100 km 40 m → Let’s check:
→ First, add all the metres: 40 + 30 + 10 = 80 m
→ So total = 60 km + 80 m → which is 60 km 80 m, NOT 100 km 40 m → False

d) 4 km = 3000 m → False
→ 4 km = 4 × 1000 = 4000 m, not 3000 m.

e) My father jogs 50 km daily → False (in real life)
→ 50 km is extremely far for daily jogging (that’s more than a marathon!). Most people jog 5–10 km max. So this is unrealistic → False

*(Note: If this were purely mathematical without context, we might say "can’t tell", but since it’s about real-life plausibility, we mark false.)*
