Metric Conversion Charts
To convert from imperial to metric, multiply by the conversion factor.
For example: 10 inches x 2.5 = 25 centimetres
To convert from metric to imperial,
divide by the conversion factor.
For example: 25 centimetres รท 2.5 = 10 inches
Imperial Conversions:
lb/acre x 0.0033 = oz/yd2
gal/acre x 0.033 = oz/yd2
