No .00 with dollars. 
Example: Tickets are $2. (not $2.00)
When using the dollar sign, don’t repeat the word dollars. 
Example: The $20-million project. (not $20-million-dollar project)
Use metric and spell out terms. 
Example: A 10-kilometre run. (not km)
A few common terms – km/hr, m.p.h. – are acceptable on second reference when used with numbers. 
Example: 50 km/h, 60-m.p.h. 
Do not use decimal points, unless it is critical that exact percentages are defined. 
Example: 12-1/2 days (not 12.5 days).
