1. Medical Math for Health Team

2. Know the abbreviations oLength/Distance - Household inch (“ or in) foot (‘ or ft) yard (yd)

3. Metric System Distance/length: meter (m) Volume: liter (L) Mass/weight: gram (g or gm) Common metric prefixes Kilo: 1000 times Centi: 1/100(100 times) Milli: 1/1000

4. Capacity/Volume - Household teaspoon (t or tsp) tablespoon (T or tbsp) ounce (oz) cup (C)-8 oz = 1 C (KNOW) pint (pt) quart (qt) » Mass/Weight - Household ounce (oz ) pound ( lb )

5. Metric conversions 1 m = 100 cm 1 m = 1000 mm 10 mm = 1 cm 1 L = 1000 mL 1 mL = 1 cc 1 g = 1000 mg 1 kg = 1000 g

6. Convert among metric and standard measurements. Memorize!! 1 in = 2.5 cm 39.4 in = 1 m 1 tsp = 5 mL 1 oz = 30 mL 1 qt = 1000 cc 2.2 lb = 1 kg Celsius to Fahrenheit ( 0 C x 1.8) + 32 = 0 F Fahrenheit to Celsius ( 0 F – 32) / 1.8 = 0 C

7. Temperature Memorize!!! Celsius to Fahrenheit ( 0 C x 1.8) + 32 = 0 F Fahrenheit to Celsius ( 0 F – 32) ÷ 1.8 = 0 C

8. Military Time Time expressed using 4 digits 0100 = 1 am 0530 = 5:30 am 1200 = noon 1400 = 2 pm 2000 = 8 pm 2400=midnight

9. 12 midnight on the dot is called 2400 (twenty-four- hundred). Once you are even a minute past, you use 0000, for this is where the 24-hour clock officially starts. An example- let's say 15 minutes past midnight. You use 0015, and you pronounce it "zero-zero-one-five." (12:15AM)

10. The trick the soldiers learn, is that whatever number you have, subtract 12 from it, and you have the regular time. Example: 1800 hours.. (18-12=6) So, 1800 hours is 6 PM. 2230 Hours (22-12=10) 2230 hours is 10:30 PM

11. A Look at 2400 clock

12. What time is 11:00 a.m. in military time?

13. What time is 5:30 pm military time?

14. Roman Numerals Roman numerals are sometimes used for medications and solutions as well as with organizing file systems in health care. I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000

15. Roman Numeral Rules No more than three of the same Roman Numerals should be used in a sequence. When the same number is next to itself, you add them together. (XX is 10+10=20) When a smaller number is before a larger one (such as in IV), then the smaller number is subtracted from the larger one. (5- 1=4) If a smaller number is after a larger one, then you add. VI would be (5+1=6)

16. Practice Makes Perfect: What is the Roman numeral for 40? Use L for 50 and X for ten and remember your rules to place them properly!! XL-subtract the smaller number X (10) from the larger number L(50)- (50-10=40)

17. Lets practice again: You need to order LXVIII boxes of probe covers for your thermometers in the medical clinical where you work. How many is this? L=50 X=10 VIII= (5+1+1+1)=8 Add all together 50+10+8=68

18. More Practice: You have CLXIV members of your high school club. How many are there? C=100 L=50 X=10 IV (remember I is smaller than V so you subtract V=5 and I=1 so 5-1=4) Add them all together 100+50+10+4=164
