beale: math calculations for pharmacy technicians, 4th edition
chapter 04: measurement systems, units, and equivalencies
show how to correctly express the following:
- two and one - half cups
- three and one - half grams
- three and one - half fluid drams
- one and two thirds pints
- eighteen liters
- ten thousand units
- forty milliequivalents
- 50 micrograms
- eight ounces (household)
- five and three quarter liters
complete the following equivalencies.
- 1 tbsp = ______ tsp
- 1 c = ______ oz
- 1 kg = ____________ g
- 1 g = _________ mg
- 1 qt = ______ pt
- fl℥ i = fl℥ ____
- fl℥ i = m℥ ______
- 1 lb = _________ oz
- 1 mg = _________ mcg
- 1 oz = _________ tbsp
Step1: Expresar fracciones mixtas como números decimales
- Dos y medio tazas: $2.5$ tazas
- Tres y medio gramos: $3.5$ g
- Tres y medio onzas fluidas: $3.5$ f℥
- Uno y dos tercios de pinte: $1+\frac{2}{3}=\frac{3 + 2}{3}=\frac{5}{3}\approx1.67$ pt
- Dieciocho litros: $18$ L
- Diez mil unidades: $10000$ U
- Cuarenta miliequivalentes: $40$ mEq
- Cincuenta microgramos: $50$ mcg
- Ocho onzas (hogareñas): $8$ oz
- Cinco y tres cuartos de litros: $5+\frac{3}{4}=5.75$ L
Step2: Completar equivalencias
- 1 Tbsp = 3 tsp (porque 1 cucharada = 3 cucharaditas)
- 1 c = 8 oz (1 taza = 8 onzas fluidas)
- 1 kg = 1000 g (por la relación entre kilogramos y gramos)
- 1 g = 1000 mg (por la relación entre gramos y miligramos)
- 1 qt = 2 pt (1 galón = 4 cuartos, 1 cuarto = 2 pintes)
- f℥ i = f℥ 8 (1 onza fluida = 8 onzas fluidas minimas)
- f℥ i = 30 ml (1 onza fluida = 30 mililitros aproximadamente)
- 1 lb = 16 oz (1 libra = 16 onzas)
- 1 mg = 1000 mcg (1 miligramo = 1000 microgramos)
- 1 oz = 2 Tbsp (1 onza = 2 cucharadas)
