Product Information

So exactly how many milligrams are there in a milliliter? The first step to answering this question is to understand what the letter 'm' means when applied to units. It means one-thousandth (1/1000) of the original unit. Therefore we're asking how many thousandths of a gram are there in a thousandth of a liter. Recall that a gram is one-thousandth of a kilogram. If you need help converting weight from a different unit to mg, our weight converter can help. The kilogram was originally defined in 1795 as equal to one liter of water at the temperature of melting ice (0 °C / 32 °F). That's not entirely true in the present day, as the kilogram and meter (a liter is the volume of one-thousandths of a cubic meter) have been re-defined, but it's very close indeed (0.9998 kg is a more precise figure).

Where P is the pressure in Pa (pascals), F is the force in N (newtons), and A is the area in m So, a milligram is a thousandth of a thousandth of a kilogram, and a milliliter is a thousandth of a liter. Notice there is an extra thousandth on the weight unit. Therefore, there must be 1,000 milligrams in a milliliter, making the formula for mg to ml conversion: Now that we've sorted that out, the question is now "What is the relationship between kilograms and liters?"

Volume

A syringe is a medical device that is used to inject fluid into, or withdraw fluid from, the body. They are also used to measure the volume of fluid in a body cavity or organ. The pressure in a syringe is calculated by the force applied to the plunger divided by the cross-sectional area of the plunger. This can be done by using the equation:
