# What is the height in metres of 50,000 £1 coins stacked?

The height in meters of 50,000 £1 coins (thickness: 2.8 mm) stacked is 140 meters.

If I was fortunate to have access to 50,000 £1 coins I would stack them up, get some ladders and a measuring tape.

Sadly, I am not so fortunate, hence I'll have to take another approach.

Using a micrometer, the thickness of a £1 coin is 2.8 mm

so, 50,000 x 2.8 => 140,000 mm

i.e. 14000 cm

Hence, 140 metres

Thinking back, using ladders and climbing 140 metres doesn't seem a good idea!!

Depends on how many millimeters thick a £1 coin is. Say it's 3 mm (?) which gives 0,003 meters x 50 000 = 150 meters

Find out how thick it is, take that times 50 000 and you have your answer.

Wikipedia says the UK pound coin is 2.8 mm thick, so 50,000 of those would be 140,000 mm, or 140 m.

The new coin is 2.8 mm thick

2.8 mm * 50000 =>

1.4 mm * 100000 =>

1.4 * 10^(-3) m * 10^5 =>

1.4 * 10^2 m =>

140 meters
