Hướng dẫn sử dụng

Để chuyển đổi một số lượng dược chất (hoặc hoạt chất), vui lòng làm theo các bước:

  • Trong trường Nhóm chất, hãy chọn một nhóm.
  • Trong trường Chất chọn một chất từ nhóm đã chọn trước đó.
  • Trong trường Số lượng nhập số lượng dược chất (hoặc hoạt chất) của bạn.
  • Trong trường Từ chọn đơn vị ban đầu.
  • Trong trường Để chọn đơn vị muốn chuyển sang.
  • Trong trường Vị trí thập phân nhập một số vị trí thập phân được hiển thị trong kết quả.
  • Nhấn nút Chuyển đổi. Kết quả sẽ xuất hiện phía dưới.

Ví dụ: Nếu bạn đã nhập 1000000 và kết quả là 0,00, vui lòng tăng độ chính xác lên 6-7 chữ số thập phân hoặc chuyển thành đơn vị nhỏ hơn. Một số chất có hệ số chuyển đổi thành một số chất khác với tỷ lệ rất nhỏ nên kết quả thu được cũng sẽ rất nhỏ. For convenience, under the rounded result unrounded one will display.

Tôi hy vọng công cụ chuyển đổi này sẽ hữu ích cho bạn!

Information about «International units»

International unit (IU) — In pharmacology, the international unit is a unit of measurement for the amount of a substance; the mass or volume that constitutes one international unit varies based on which substance is being measured, and the variance is based on the biological activity or effect, for the purpose of easier comparison across substances. International units are used to quantify vitamins, hormones, some medications, vaccines, blood products, and similar biologically active substances. Many biological agents exist in different forms or preparations (e.g. vitamin A in the form of retinol or beta-carotene). The goal of the IU is to be able to compare these, so that different forms or preparations with the same biological effect will contain the same number of IUs. To do so, the WHO Expert Committee on Biological Standardization provides a reference preparation of the agent, arbitrarily sets the number of IUs contained in that preparation, and specifies a biological procedure to compare other preparations of the same agent to the reference preparation. Since the number of IUs contained in a new substance is arbitrarily set, there is no equivalence between IU measurements of different biological agents. For instance, one IU of vitamin E cannot be equated with one IU of vitamin A in any way, including mass or efficacy. Despite its name, IU is not part of the International System of Units used in physics and chemistry. The IU should not be confused with the enzyme unit, also known as the international unit of enzyme activity and abbreviated as U.

International unit (IU) — Internationally agreed-upon standards are necessary to compare the potency of various biologically assayed compounds in terms of their activity. If it is not possible to purify chemically the substance to be bioassayed, a stable standard solution has to be employed for comparison. Standards for sera are held at the State Serum Institute, Copenhagen, the National Institute for Medical Research at Mill Hill, UK. and by the WHO. An International Unit is defined as a particular quantity of the standard preparation (one IU of tetanus antitoxin is 0.1547 mg of a preparation held in Copenhagen).

  • Added colistimethate sodium (conversion to colistin base or vice versa). This conversion required in the case of inhalation administration of colistimethate sodium. The conversion works either in the direction of [IU of colistimethate sodium in mg/g of colistin base) or in the direction of [mg/g of colistin base in IU of colistimethate sodium].
  • Reviewed all substances and their conversion factors. Added links on reliable sources for each substance.
  • Deleted controversial substances with not confirmed data.
  • Substances divided into groups.
  • Edited names of some substances.
  • Added synonyms for some substances.
  • Added unrounded result to the output. It is useful when you get zero result. Unrounded result will show that you have to change target units to smaller (for example from mg to mcg).
  • Converter is optimized for mobile devices.
