† When there is risk of confusion with the symbol for radian, rd may be used as the symbol for rad. Units in use temporarily with the SI Name The term “metric ton” is preferred for use in the US. § The terms tonne and “metric ton” are restricted to commercial usage the SI equivalent is the megagram. ‡ The symbol “L” is preferred for use in the US, Canada, and Australia. It is included here as it is commonly used for rotational speed. † Technically, a revolution is a semantic annotation and not a unit. The symbols for minute and second are prime and double prime ( not single and double quotation marks), respectively. * Decimal degrees should be used for division of degrees, except for fields such as astronomy and cartography.

Non-SI units accepted for use with the SI Quantity * The radian and steradian, previously classified as supplementary units, are dimensionless derived units that may be used or omitted in expressing the values of physical quantities. Before MathQuill was in use the units had to be preceded by a space (in most cases).SI derived units with special names and symbols QuantityĮlectric potential difference, electromotive forceĪbsorbed dose, specific energy imparted, kermaĭose equivalent, ambient dose equivalent, directional dose equivalent, personal dose equivalent, organ dose equivalent In some cases, pressure of gases is measured as the difference. This prevents MathQuill from rewriting the units in two dimensional typeset form. The SI unit for pressure is the pascal, which is a newton per square meter. It is a measure of force per unit area, defined as one newton per square meter. 9.81 'm/s^2 which invokes text mode (tT) for the units. The pascal (symbol: Pa) is the SI derived unit of pressure, internal pressure, stress, Youngs modulus and tensile strength, named after the French mathematician, physicist, inventor, writer, and philosopher Blaise Pascal. If MathQuill (the vertical math pallet on the side of the page) is being used then the unit should be preceded by a double quote - e.g. Units need to come at the end of the answer blank. In some problems, you may need to combine units (e.g, velocity might be in ft/s for feet per second). Below is a list of basic units and how they need to be abbreviated in WeBWorK answers. Some WeBWorK problems ask for answers with units. The abbreviations for units that are recognized by WebWork are:ġ atm = 14.7 lb/in^2 = 1.01E5 Pa = 1.01E5 kg/m*s^2 There may be only one / in a given compound unit expression and no spaces are allowed within the units expression. The string of units before the / denote the numerator of the compound expression, while those following the / denote the denominator of the compound expression. Where i is any of the unit abbreviations listed below, and the n i are positive or negative integers. The units may be any compound expression of the form: Note that trigonometric functions assume the argument is expressed in radians and not degrees. To see the syntax required for such expressions, as well as to see which special functions and numerical constants are recognized, see the section on Available_Functions. We assume you are converting between kilonewton/square millimetre and megapascal.You can view more details on each measurement unit: KN/(mm2) or MPa The SI derived unit for pressure is the pascal. How many KN/(mm2) in 1 MPa The answer is 0.001. For example, (6+4)/2 is the same as writing 5. More information from the unit converter. In place of a specific number for the numerical part of an answer, you may also use algebraic expressions. The numerical value may be written as a floating point decimal, for example 0.00314159, or in scientific notation as either 3.14159E-3 (as in FORTRAN) or 3.14159*10^-3 (with * signifying multiplication, and ^ signifying exponentiation note in using the FORTRAN-like notation, you must use capital 'E' and not small 'e'). If a MathQuill pallet is being used then a double quote (which invokes text or tT mode) must separate the value from the units: for example 9.18 'm/s^2 Numerical values If no MathQuill pallet is present a space must separate the numerical value from the units, as in for example 1.234 m. Most answers consist of a numerical value followed by an abbreviation for the appropriate units of the physical quantity. 1 Problems requiring a numerical answer.
