Imperial ↔ Metric Unit Conversions
Tags: units, imperial, metric, day to day, useful
Conversions from common imperial units (foot, acre, cup, pound, etc) to their metric counterparts and vice versa.
All conversion factors are taken from Google and truncated to 4 digits after the decimal point. You probably don’t want to actually memorize to that precision (unless you’re crazy or your mental arithmetic is really good) so I would manually truncate the cards further after you download them.
The “Definitions” field is from Wikipedia’s conversion of units page.
I selected what I felt to be the most useful conversion factor, e.g. inches ⇔ centimeters rather than having all length units in terms of meters.
