What is ...

Gunter's Chain


It all started when...

... in 1616 a man named Edmund Gunter invented a tool that revolutionized measuring land for the next 300 years. It was a simple chain but more importantly it was a system of measuring in common units. The chain was 66 feet long. A mile was evenly divisible by Gunter's chain and so were acres.
