Formula for Temperature:

Celsius to Fahrenheit

Exact:
9/5 C + 32 = F

Approximately:
C x 2 ~ F

Rough Example:
.1C ~ .2F

The 'Approximately' and the 'Rough Example' conversions should be used only to figure changes to the original temperature, not for converting an absolute temperature. For example, finding out how much difference 3/10 of a degree is OK, but, 'what is 68 degrees F equal to in C' is not correctly converted (because of the 32 degree shift, plus or minus). Note: Some references may use the name 'centigrade' instead of 'Celsius', they mean the same thing.

Fahrenheit to Celsius

Exact:
5/9 (F - 32) = C

Approximately:
F x .5 ~ C

Rough Example:
1F ~ .05C

Formula for Volume:

Milliliters to Ounces

Exact:
ml / 29.5737 = oz

Approximately:
ml / 30 ~ oz

Rough Example:
90 ml ~ 3 oz

Ounces used for conversion are US fluid ounces. 8 oz = 1 US cup. 16 oz = 1 US pint (pt.) 32 oz = 1 US quart (qt.) 128 oz = 1 US gallon (gal.) 1 ml = 1 cubic centimeter (cc.) 1000 ml = 1 liter (l.) Note: 'Liter' is sometimes spelled 'litre.'

Go to Conversion Table.

Formula for Volume:

Ounces to Milliliters

Exact:
oz / 0.0338 = ml

Approximately:
oz / 0.03 ~ ml

Rough Example:
1 oz ~ 30 ml

Go to Conversion Table.

Formula for Length:

Millimeters to Inches

Exact:
mm / 25.40 = in

Approximately:
mm / 25 ~ in

Rough Example:
25mm ~ 1in

10 mm = 1 cm (centimeter), 1,000 mm = 1 m (meter), 12 in = 1 foot, 3 foot = 1 yard.

Go to Conversion Table.

Formula for Length:

Inches to Millimeters

Exact:
in / 0.03937 = mm

Approximately:
in / 0.04 ~ mm

Rough Example:
1 in ~ 25mm

10 mm = 1 cm (centimeter), 1,000 mm = 1 m (meter), 12 in = 1 foot, 3 foot = 1 yard.

Go to Conversion Table.

Formula for Weight:

Grams to Ounces

Exact:
gm x 0.03527 = oz

Approximately:
gm x 0.03 ~ oz

Rough Example:
30gm ~ 1oz

Ounces used for conversion are US weight ounces (avoirdupois). 16 oz = 1 pound (lb.) 1000 grams = 1 kilogram (kg.)

Go to Conversion Table.

Formula for Weight:

Ounces to Grams

Exact:
oz x 28.349 = gm

Approximately:
oz x 30 ~ gm

Rough Example:
1oz ~ 30gm

Ounces used for conversion are US weight ounces (avoirdupois). 16 oz = 1 pound (lb.) 1000 grams = 1 kilogram (kg.)
