Units in WeBWorK

Here are some examples of answers that require units.


Answers with units WeBWorK accepted forms
\(2.5\) (unitless) 2.5 unitless
\(2.5 \;\text{m}\) 2.5 m
250 cm
2500 mm
0.0025 km
\(2.5 \;\text{m}^2\)
2.5 m^2
\(2.5 \;\text{m/s}\)
2.5 m/s
\(2.5 \;\text{N}\cdot\text{m}\)
2.5 N*m
\(2.5 \;\text{/s} = 2.5 \;\text{s}^{-1}\) 2.5 unitless/s
2.5 s^-1
\(2.5 \;\frac{\text{kg}\cdot \text{m}^2}{\text{s}^2}\)
2.5 kg*m^2/s^2
2.5 kg*m^2*s^-2
\(2.5 \;\frac{\text{s}^2}{\text{kg}\cdot \text{m}^2}\) 2.5 s^2/(kg*m^2)
2.5 s^2*kg^-1*m^-2
\(2.5 \;\frac{\text{kg}}{\text{m}/\text{s}^2} = 2.5 \;\frac{\text{kg}\cdot\text{s}^2}{\text{m}}\) 2.5 kg*s^2/m
2.5 kg*s^2*m^-1
