3000 mm
4.5 m = 4500 mm. There are 10 mm in a cm, 100 cm in a m and therefore 1000 mm per m.
.147 m 1000 mm = 1 m
10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km So 1 x 1000 x 100 x 10 = 1000000 mm.
(7.5 m) x (100 cm/m) x (10 mm/cm) = (7.5 x 100 x 10) = 7,500 mm
It is 10 metres.
3000 mm
4.5 m = 4500 mm. There are 10 mm in a cm, 100 cm in a m and therefore 1000 mm per m.
2 mm = 0.002 m.
98 m = 98000 mm.
702 m = 702,000 mm
.147 m 1000 mm = 1 m
1700 mm
10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km So 1 x 1000 x 100 x 10 = 1000000 mm.
It is 0.032 m.
The milli- (m) prefix means 1/1000 = 10⁻³ The Giga- (G) prefix means 10⁹ → 1 Gm ÷ 1 mm = (1 × 10⁹)m ÷ (1 × 10⁻³)m = 10⁹ × 10³ = 10¹² → There are 1,000,000,000,000 mm in 1 Gm.
1000 mm = 1 m so 6310 mm = 6.31 m. Simple!
