Conversion Formulas and Tables
Metric to English,
English to Metric
Most of the world, with the exception of the USA, uses the metric system of measurements exclusively. In the USA there are many people that choose to use the metric system. There are also those who are unfamiliar with, or just don’t 'like' the metric system.
JOBO is an international company. As such, we want to be able to provide information that is understandable to as many different people as possible. To this end, we try to include both metric and English measurements whenever possible.
You may find other sources that publish information exclusively in only one of the measurement systems. These tables will help those who are not familiar with one system to be able to convert to 'their' system of measures.

Celsius to Fahrenheit
Exact:
9/5 C + 32 = FApproximately:
C x 2 ~ FRough Example:
.1C ~ .2FThe '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) = CApproximately:
F x .5 ~ CRough Example:
1F ~ .05CThe '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.

Milliliters to Ounces
Exact:
ml / 29.5737 = ozApproximately:
ml / 30 ~ ozRough Example:
90 ml ~ 3 ozOunces 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.
Ounces to Milliliters
Exact:
oz / 0.0338 = mlApproximately:
oz / 0.03 ~ mlRough Example:
1 oz ~ 30 mlOunces 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.'

Millimeters to Inches
Exact:
mm / 25.40 = inApproximately:
mm / 25 ~ inRough Example:
25mm ~ 1in10 mm = 1 cm (centimeter), 1,000 mm = 1 m (meter), 12 in = 1 foot, 3 foot = 1 yard.
Go to Conversion Table.
Inches to Millimeters
Exact:
in / 0.03937 = mmApproximately:
in / 0.04 ~ mmRough Example:
1 in ~ 25mm10 mm = 1 cm (centimeter), 1,000 mm = 1 m (meter), 12 in = 1 foot, 3 foot = 1 yard.

Grams to Ounces
Exact:
gm x 0.03527 = ozApproximately:
gm x 0.03 ~ ozRough Example:
30gm ~ 1ozOunces used for conversion are US weight ounces (avoirdupois). 16 oz = 1 pound (lb.) 1000 grams = 1 kilogram (kg.)
Go to Conversion Table.
Ounces to Grams
Exact:
oz x 28.349 = gmApproximately:
