| 1 kg | = | 2.2 lbs | = | 1000 gms | ||
| 1 gr. | = | 64.8 mg. | ||||
| 1 mg | = | 1000 mcg (ug) | ||||
| 1 mcg | = | 1000 ng (nanograms) | ||||
| 1 oz | = | 28.4 gms | ||||
| 1 gm | = | 1000 mg | = | 15 gr | = | 0.0022 lbs |
| 0.05 gm | = | 50 mg | = | 3/4 gr | ||
| 0.03 gm | = | 30 mg | = | 1/2 gr | ||

Sample Weight Conversions |
||||
| To convert kilograms (kg) to pounds (lbs): Multiply the number of kilograms by 2.2 | ||||
| Example: | ||||
| 2 kg | x | 2.2 | = | 4.4 lbs |
| 5 kg | x | 2.2 | = | 11 lbs |
| To covert pounds (lbs) to kilograms (kg) can be done either of two different ways: | ||||
| ——Divide the number of pounds by 2.2 | ||||
| Example: | ||||
| 2 lbs | / | 2.2 | = | 0.9 kg |
| 2.2 lbs | / | 2.2 | = | 1 kg |
| ——Multiply the number of pounds by 0.454 | ||||
| Example: | ||||
| 2 lbs | / | 0.454 | = | 0.9 kg |
| 2.2 lbs | / | 0.454 | = | 0.99 or 1.0 kg (if rounding off) |
| To convert grams (g) or (gm) to pounds (lb). Multiply the number of grams by 0.0022 | ||||
| Example: | ||||
| 454 gm | x | 0.0022 | = | 0.99 lb or 1.0 lb (if rounding off) |
| Example: | ||||
| 1000 gm | x | 0.0022 | = | 2.2 lbs |
| To convert pounds (lb) to grams (gm) or (g). Multiply the number of pounds by 454 | ||||
| Example: | ||||
| 2 lbs | x | 454 | = | 908 gm |

Calculation Setups |
||||
| Need a little help in figuring the dosage or volume needed? Here are a couple of formulas for you to follow. | ||||
| I also find that the second formula helps when you wish to know correct dose per weight. See the second example in the second formula. | ||||
| First Formula: | ||||
| (desired)/available | x | volume | = | what you will give |
| Second Formula: | ||||
| (mg avail)/in mL avail | x | (mg wanted)/? mL | = | mL you will give |
| (recommended dosage)/recommended weight | = | (? desired dosage)/your rat’s weight | ||
