| What is an easy way to remember conversions of gr to mg? | The grain clock
The grain clock is thinking of the face of a clock and applying gr to mg like this. 1hr=60min, gr1=60mg, 1/4hr=15min, gr1/4=15mg, 1/2hr=30min, gr1/2=30mg, 3/4hr=45min, gr3/4=45mg |
| 1/4hr=___mins | 1/4hr=15mins |
| 1/2hr=___mins | 1/2hr=30mins |
| 3/4hr=___mins | 3/4hr=45mins |
| 1hr=____mins | 1hr=60mins |
| gr1/4=___mg | gr1/4=15mg |
| gr1/2=___mg | gr1/2=30mg |
| gr3/4=___mg | gr3/4=45mg |
| gr1=____mg | gr1=60mg |
| gr1/4=___mg | gr1/4=15mg |
| gr1/2=___mg | gr1/2=30mg |
| gr3/4=___mg | gr3/4=45mg |
| gr1=____mg | gr1=60mg |
| gr1/4=___mg | gr1/4=15mg |
| gr1/2=___mg | gr1/2=30mg |
| gr3/4=___mg | gr3/4=45mg |
| gr1=____mg | gr1=60mg |
| 1/4hr=___mins | 1/4hr=15mins |
| gr1/4=___mg | gr1/4=15mg |
| gr1/150=___mg | gr1/150=0.4mg
here is still the same numerals, a 1, a 5, and a 4 just reversed on the sides of the equation with zero's added. |
| 1/150hr=____mins | 1/150hr=0.4mins
1hr=60mins. 60mins. divided by 150 = 0.4mins |
| gr1/150=____mg | gr1/150=0.4mg
gr1=60mg. 60mg divided by 150 = 0.4mg |
| gr1/150=____mg | gr1/150=0.4mg |
| gr1/150=____mg | gr1/150=0.4mg |
| gr1/150=____mg | gr1/150=0.4mg |
| 1/2hr=____mins | 1/2hr=30mins |
| gr1/2=____mg | gr1/2=30mg |
| 1/300hr=___mins | 1/300hr=0.2mins |
| gr1/300=___mg | gr1/300=0.2mg |
| gr1/300=___mg | gr1/300=0.2mg |
| gr1/300=___mg | gr1/300=0.2mg |
| gr1/300=___mg | gr1/300=0.2mg |
| gr1/300=___mg | gr1/300=0.2mg
here is still the same numerals, a 1, a 2, and a 3 just reversed on the sides of the equation and zeros added. |
| 1/300hr=___mins | 1/300hr=0.2mins
1hr=60mins. 60mins. divided by 300 = 0.2mins |
| gr1/300=0.2mg | gr1/300=0.2mg
gr1=60mg. 60mg divided by 300 = 0.2mg |
| gr1=___mg | gr1=60mg |
| gr15=____mg | gr15=1000mg
gr15 X 60mg = 900mg but rounds up to be 1000mg or 1g |
| gr15=____g | gr15=1g |
| gr15=____g | gr15=1g |
| gr15=____g | gr15=1g |
| 1g=gr____ | 1g=gr15
Since a paperclip weighs 1g think of stretching out the paperclip and cutting it into 15 pieces holding the pieces in your hand they may look somewhat like 15 grains of rice. |
| 1g=gr____ | 1g=gr15 |
| 1g=gr____ | 1g=gr15 |
