I still weigh myself in Stones & Pounds

I measure my height in Feet and Inches

I drink pints

I recently bought some land was that measured in acres

My speedo reads mph, signs gives distances in miles.

I measure cold temperatures in Celsius and hot ones in Fahrenheit.

We as a nation are nominally bi-lingual between metric and imperial and happily use both depending on the scenario.
