MILES OR METERS
Having grown up enmeshed in metric and imperial both measurements come naturally to me (except Fahrenheit, with freezing point of water at 32o and boiling point at 212o I still find it difficult to visualise, and altitude of aircraft which I still find impossible to visualise in meters, but as the international standard for aircraft height is Feet I think I’m OK there). So I have slipped into the lazy habit of interchanging meters and feet, miles and kilometres in the stories. This inconsistency is wrong and I am in the process of turning everything into Imperial but it is taking time so… I apologise to the readers for the inconvenience.
These are approximate conversions
1 inch ~ 2.5 cm
1 yard ~ 1 meter
1 mile ~ 1.6 kilometres
