unit conversion quiz on Monday September 27th!
In the last post we learned about unit conversions! To recap unit conversions:
- convert 2 mg to grams
- start by writing out the equation:
- 2 mg x 10^3 mg/1 g
- to get 2 x 10^-3g or 0.002g
To continue with unit conversions, let us try a more complicated conversion:
- convert 10km/h to m/s
- we now have 2 units that need to be converted; km to m and h to min to s
- let's start by writing out the equation:
1h 1km 60min 60s
- we than cancel out units and multiply:
10km x 10^3m x 1hx 1min
1h 1km 60min 60s
- to get 2.77777778m/s or 2.8m/s
...a table of unit conversions!
have fun on the long weekend, and study hard!
