Enter a number into the larger box at the top, to calculate the smaller proportional value in the box below, or vice-versa enter a number into the smaller box at the bottom, to calculate the larger proportional value in the box above. Confused? Oh come on, read all that again. Got it? Ok good.
Indicates which way you are performing the calculation, up or down the ratio, small to large or large to small.
Switch to Φ INT (phi, integer) mode to get your calculations as integers i.e. rounded to the nearest whole number, no decimals.
Switch back to Φ and they'll be calculated to 12 decimal places.
